The suite of DeeperWeb enhancements to Google results include tag clouds, metrics, Q&As, and results from specific sources such as journalism sites, blogs, and Wikipedia. And unlike other next-gen search engines, DeeperWeb plays nice with Google, allowing users to maintain the familiarity of the Google interface and the reliability of Google results while experimenting with new paradigms.

The tag clouds in particular are helpful for suggesting new keywords or areas to search, and users can click terms to instantly add or exclude them and get more focused results.

According to DeepCloud's website, businesses and marketers can also use the tags as a simple, fast, and free means of "identifying main competitors, pinpointing targeted sites for most effective advertisement, and isolating the authoritative websites of a particular topic." While larger companies would have far more sophisticated tools at their disposal, this could be a good starting point for small businesses.

Narrowing search results by source and type of media also has great implications for individual productivity. For example, searching for statistical information on peanut butter using Google alone yields strange and limited results and takes quite a bit more time than Googling "peanut butter" and letting DeeperWeb's Metrics tab sort out the empirical data on that most sticky of condiments.

Better yet, co-founder Alex Rinsky said in a phone conversation this afternoon that the next version, slated to be released in 2-3 weeks, will allow users to further narrow news results based on industry (business, tech, general, etc.) and will provide options for searching for video, podcast, slide deck, and other multimedia results.

The latest addition to their collection of utilities is a new, experimental Firefox extension called the Pixelpipe Media Uploader 1.0. With this add-on, you can upload media all across the social web either through drag-and-drop or by selecting from a chooser.

After installing the extension and restarting Firefox, you'll see that there's a new orange "P" button in your toolbar. Click that once and the Pixelpipe sidebar will display on the left side of the screen. The first time you go to use this tool, you'll need to sign in with your Pixelpipe account and authorize it to work in Firefox. Once that's done, you can then drag-and-drop any media into the sidebar to upload it to Pixelpipe which then, of course, shoots it out to any of the services you've configured. Alternately, you can right-click on any image on the web and choose the "Upload image with Pixelpipe Uploader" option from the menu that appears.

One of the nice things about the uploader is that you can add the title, any appropriate tags, and set the privacy levels before you click "Upload." That way, you don't have to actually go visit the sites afterwards to configure these sorts of settings. 

This new utility is just another reminder of how desktop software tools are slowly being replaced by browser-based services. Who needs the Flickr uploader anymore when you can drag photos to your browser and send them directly to Flickr, Facebook, and a slew of other sites with only a click or two?

If you want to try the new Pixelpipe Media Uploader, you can download the Firefox extension here.

Oliver Reichenstein and Aza Raskin, head of user experience at Mozilla, have been thinking about the future of tabs in Firefox, and some of the resulting mockups are quite intriguing.

Reichenstein argues that tabs were a good solution for an earlier age of the Internet, when users hardly ever had more than ten tabs open at any given time. Now, however, as browsers are slowly turning into operating systems, a new paradigm for organizing this information has become necessary.

The current generation of browsers does a decent job when it comes to keeping a current browser session organized, but Reichenstein wants to create a system that structures the browser more like a mutimedia file system. He proposes a new interface that looks more like iTunes than today's Firefox, with folders, libraries, and bookmarks in a sidebar.

Try Tree Tabs

If you would like to get a glimpse of what tabs on the side look like, have a look at Tree Tabs, a nifty addon that puts tabs on the side and that features a huge number of options for customizing the experience.

If you are on a netbook, for example, where vertical space is very limited, Tree Tabs (maybe in combination with Tiny Menu) will allow you to reclaim some of your screen estate.

Coming Soon: Built-In Ubiquity

Mozilla is also moving ahead with the integration of Ubiquity, a command-line style interface for common browser tasks, into Firefox's 'awesome bar.' Mozilla plans to add this project, dubbed Taskfox, into the main Firefox interface by the time version 3.6 of Firefox is released.

You can find an interactive demo here, or have a look at the mockups on this page.

First and foremost, the biggest news regarding the latest release is definitely the added support for Linux operating systems. In order for Cooliris to work on Linux, you need to run a recent Linux distribution (e.g. Ubuntu 8.04, Fedora 10, OpenSuse 11). You'll also need hardware-accelerated graphics, Flash 10+, and Firefox 3.

Another new feature is the software's ability to now view files that are saved on your own computer. At the moment, this local media support is limited to photos only, but the company is working on adding video support in a later release. In a way, this makes the browser plugin behave somewhat like desktop software as it blurs the line between what's online and what's not. Just as you can browse through Flickr, Facebook, Picasa, and Google Images, you can now click on an item that reads "My Computer" to gain access to your local media store, too.

Finally, the software has been upgraded to include additional metadata about the content you're viewing. This may seem like an inconsequential upgrade, but it actually may be the most useful of them all. Instead of simply browsing through the photos or videos, you can now see additional information like ratings, view counts, title, resolution, etc. If you're flipping through the Facebook photos, you can easily move from one friend's photos to another's by clicking the names of the people tagged in the photo, accessible from the metadata section at the bottom of the image. This upgrade also applies to items in the "Shopping" section of the plugin where you can virtually window shop at Amazon.com.

Glorious Metadata!

Coming Soon: A New Cooliris for iPhone

Cooliris is also releasing an upgrade for their iPhone application, too, which will include some of the same features as the browser plugin. One notable exception, however, is that it won't have the ability to browse through the photos stored locally on the device itself. This is because Apple prevents the application from tapping into that local store, explains Shashi Seth, the company's Chief Revenue Officer. That said, the new iPhone app will display metadata, which should make it a more useful way to surf through your online media, go shopping, or catch up on the news.

Cooliris Raises $15.5 M

The company also announced that it has completed $15.5 million in Series B funding from a group of investors including Kleiner Perkins Caufield & Byers, DAG Ventures, The Westly Group and the T-Mobile Venture Fund.

The software, originally launched in January 2008, has been downloaded over 10 million times and is seeing 50,000 new downloads per day. The iPhone app has reached 800,000 downloads.

Reframe It also announced that it has added Lawrence Lessig, John Seely Brown, Terry Winograd, and Clay Shirky to its Advisory Board, which already includes an all-star line-up of Internet luminaries like Esther Dyson, Henry Louis Gates Jr, and Howard Rheingold.

Recommended by Mozilla

Reframe It also recently became a recommended addon by Mozilla, which should allow the company to grow its user base at an even faster rate.

Facebook and Twitter Integration

Reframe It's Facebook and Twitter integration works just as advertised. Given that Reframe It is still a small service, these new features will not only provide more visibility to Reframe It, but they will also allow users to start a discussion on the service and then take it to their favorite social network, where the rest of their friends and colleagues can chime in.

Brian T. McKinney, Reframe It's co-founder and Chief Technology Officer, tells us that the service will support Twitter's oAuth implementation in the second half of April, but for now, you still have to enter your full Twitter username and password to use the service.

How Does it Work?

We really like Reframe It's approach to social annotations, and the user interfaces of its web service and Firefox plugin are easy to use and very efficient. Once you have signed up for Reframe It and installed the plugin, the extension lives in your sidebar and will show any public annotations that other users have left by default. To add your own annotations, you just have to highlight a chunk of text and Reframe It will automatically use this as the anchor for your annotation. Through this, you can basically write comments into the margins of the Internet.

Fishkin told us that a lot of Reframe It's users utilize the service in a professional setting to annotate legal texts, for example, but a lot of users also use it in a school setting. Thanks to Reframe It's private groups, your annotations can stay private, though you can also choose to make your comments available to all Reframe It users.

Reframe It is clearly on to something, and thanks to its stellar advisory board and the team's clear vision for where they want the service to go, we expect to hear a lot more from them in the future. Other services like Diigo, for example, offer very similar services, however, and it remains to be seen which service users will prefer in the long run.

When you click the "Get Started" button in the Friends on Fire Facebook application, you're redirected to Yahoo's Fire Eagle page where you have to sign in with a Yahoo ID. If you don't already have one, then you'll need to create one here - an extra step that may be a bit off-putting for new users.

Once you've signed in, you must provide an email address for receiving important updates from Fire Eagle. You then must also specify at what intervals you want to receive an email that asks if you're still comfortable sharing your location. The choices you're given are "once per month," "once every 3 months," and "don't bother." Finally, you have to accept the terms of service and give the Facebook app access to your location.

Back in Facebook, you'll be shown the other Fire Eagle users among your friends and given the opportunity to connect with them. You can also configure additional settings like how exact the location updates are, who can see them on the map, and whether or not the posts update your wall.

Mobile Updaters

Of course, if you're out and about, you're not necessarily going to be hauling around your computer with you. Instead, you'll want to grab one of the mobile Fire Eagle updaters from Yahoo's Gallery. These apps include simple mobile updaters like Fire Fone for the iPhone as well as more robust social networking apps like Brightkite. However, even though these apps are integrated with Fire Eagle, we had some problems getting one of them to also update the Facebook Fire Eagle map. Our preferred mobile social network Brighkite, for instance, updated our Wall but the Fire Eagle map did not show our location.

According to Tom Coates, the head of the Fire Eagle project, it might take a couple of minutes for your location to show up when you use a third party application, but we've waited for 20 minutes so far and the Brightkite update never made its way to the map. Obviously, this delay could hamper the usefulness of a location-aware app - especially if you're checking in at places you're only going to be for a short while - like the local coffee shop or a restaurant where you stopped for lunch.

There are several apps in the list to try, so it looks like we'll need to check them one-by-one to see if that's a common issue, or something specifically related to Brightkite. (Share your experiences in the comments!)

Fire Eagle Updater for Firefox

The Fire Eagle Firefox add-on is much simpler to use. After installing the extension, you only need to click a button in your browser toolbar to update your location. This is useful for those scenarios when you are, in fact, toting your laptop around. It's easy to imagine college students using this on campus, traveling business executives checking in as they launch their browsers in airports and hotel rooms, or web workers checking in from their favorite Wi-Fi hotspots.

Both the add-on and the new Facebook application will help push the concept of location-awareness even further into the mainstream. Although, as we mentioned yesterday, the next step after location-aware apps may be location-aware ads. However, we're still excited to see the developments taking place in this area, especially when it comes from a standards-based platform with strong privacy controls like Yahoo's Fire Eagle.

Back in December, we noticed that a new developer had begun working on the MySocial24x7 extension, albeit unofficially, when he posted a note on his blog. The developer, one Dave Hodson, was once the CTO of a company called MessageCast which was acquired by Microsoft in 2005. He now works on the Windows Live RSS team, according to his bio.

Hodson had posted on his blog about how he updated MySocial24x7 so it would work with the latest version of Firefox 3. He had also fixed a few bugs including issues with Twitter authorization and posting to FriendFeed. At the time of the post, Hodson said that he emailed Sandosh for permission to continue work on the add-on and to see if Sandosh would be interested in hosting the new version on his domain.

Fast-forward to a couple of months later, and we finally have an update on where this project is going: Hodson has officially taken over the development of this extension. With permission from Sandosh (who is apparently now working on a gDocs sidebar instead), Hodson will take responsibility for the maintenance and new features of the MySocial24x7 add-on. He submitted the updated extension to Mozilla and it's currently available for download from here on addons.mozilla.org.

About MySocial 24x7

If you never gave the add-on a spin the first time around, you should check it out. Essentially, it functions the same as it did before - MySocial24x7 sits in the Firefox sidebar giving you quick access to your FriendFeed stream. Buttons at the top let you quickly switch from the "Everyone" stream to your friends' stream or even to your own. You can both "like" and comment on the items posted, view comments from others, or share items of your own.

A scrollable row of icons lets you filter the streams by service - a feature which is especially handy if you like using FriendFeed as a Twitter client. You can also filter the view by selecting just one of your friends from the drop-down list provided. Sadly, there's no option to filter by lists or rooms.

Although functional, it looks like there are still some kinks to work out with the new version. The sidebar doesn't always close when hitting the "X" and there seems to be no way to disable the pop-ups that appear (and occasionally remain) outside of the sidebar. Also, the one feature which we really wanted - an auto-refresh - is nowhere to be seen. Refreshes still have to be done manually by pressing a button at the bottom.

Still, for those with limited desktop real estate, MySocial24x7 is a decent way to keep an eye on FriendFeed throughout the day without having to visit the web site. Now that the extension works again, we hope to see some improvements, such as the ones we've noted here, added to it soon.

Do we all have our personal blind spots when it comes to security?

More Noise to Signal

Ambient News is a new Firefox add-on written by Mozilla developer Atul Varma and is currently available as an alpha release. The add-on tracks your browsing habits, learning which sites you visit most frequently. It then pulls the headlines in from those sites and displays them for you in a beautifully fading list every time you open a new tab in Firefox. If you see something that interests you, just click the link and you'll be taken to the web site where the headline originated. Privacy advocates, rest assured - no data is shared outside your browser.

Intelligent Agents to the Rescue!

As Michael Calore of Wired notes, the add-on is a great workaround for the biggest usability problem facing RSS. "Many people don't know what it is or how to take advantage of it," he writes. "The first hint that a feed exists is a funky orange or blue icon. Click on it and, in most cases, you get prompted to load another application. Sometimes, you just see ugly, raw XML output."

But since we're mostly web geeks here at ReadWriteWeb, we're more enthralled with another aspect to this tool: its intelligence. As we mentioned not too long ago, cloud agents are on the rise. The term, coined by blogger Chris Arkenberg, refers to automated agents that help us better deal with the volumes of data we have to sort through every day. Although Ambient News isn't necessary a full-on cloud agent - it doesn't actually work in the cloud - it can still certainly be considered an agent, especially since it helps us sort through a barrage of information in a new way.

Other Alternatives

Ambient News is not the only alternative to the traditional RSS Reader. Over the past year at ReadWriteWeb, we've also made mention of other alternative news readers like Feedly, which puts a magazine-style interface on top of Google Reader. Another popular RSS reader is Snackr, an Adobe AIR app that scrolls headlines across your screen like a news ticker. Then there is, of course, FriendFeed, a lifestreaming application that's quickly becoming an alternative way to share information among the early adopter set.

Alternative RSS readers aren't for everyone, though - journalists, bloggers, researchers, and the like may still need to use a jam-packed feed reader in order to seek out the elusive info they seek on a regular basis. But for those of you who are more casual web surfers and blog readers, alternative RSS readers are a less stressful way to get your news without the news getting to you.

One of these evolutions started quietly in 2008. We are witnessing the rise of a new kind of web: contextual. You might not have heard or thought about it much yet, but you are already using it today. Search remains the killer app on the web, but context is quickly become a viable contender. Why? Because context is what happens instead of search.

Until recently on the web, most sites have not been software - only data, a bunch of flat HTML pages. The software that you used to look at them was, of course, the web browser. The problem was that the browser had no idea what the pages contained, and it did not know what you were doing. Because the browser could not infer your context, it could not help you explore related and relevant information.

The contextual web experience is fundamentally different because there is an understanding of what the user is doing. The combination of the information on the page and the user's behavior creates the context. Once you understand the user's context, you can be more helpful. So, contextual technologies have the potential to bite into the pie that today belongs to search, because it is able to bypass search.

Consider the difference between looking at the IBM home page and a movie page on Netflix. The context is very different, and so likely is the user's intention. The user may be looking at IBM because she is looking for a job or researching IBM products. When the user is looking up a movie, it is because she is thinking about renting it.

The Key Properties of The Contextual Web

The Contextual web will happen when browsers and websites evolve to recognize what users are trying to do. It is the web with less choice and more meaning, where instead of Googling all the time, we Google once and then the rest of the information is available to us automatically, based on our current context.

Here are the key properties of the contextual web experience:

• Relevancy: understanding the user's context better drives content relevancy.
• Shortcuts: contextual shortcuts reduce the need for raw search.
• Personalization: context is based on user intentions and history.
• Remixing: relevant information from around the web is instantly available.

What are some specific examples of contextual technologies that are improving our web experience right now?

Markup Technologies

One of the keys to inferring user context is understanding the underlying information that the user is looking at. This is why the contextual web is related to -- and, to be more precise, is powered by -- semantic web. We have written a lot here on ReadWriteWeb about semantic technologies. Notably, we discussed the difference between the top-down and bottom-up approaches to semantic web, both of which are important for understanding the contextual web.

The bottom-up approach to context is about annotating pages. For example, all modern browsers can detect if the page you are looking at contains an RSS feed. This happens because the browser looks for a tag in the head of the page, which declares type . The fact that the page offers an RSS feed creates an obvious context: subscription. So, the browser then invites you to subscribe using your favorite RSS reader.

Another form of markup that has been discussed recently is microformats, which offer an XHTML-compliant way of embedding metadata about people, places, events, and reviews in existing web pages. Even though microformats are not ubiquitous today, there are clear benefits to using them. The image below is from an excellent post by Mozilla UI lead Alex Faaborg about leveraging microformats in the browser.

Building on the hAtom microformat are Web Slices, introduced by Microsoft in Internet Explorer 8. Web Slices enable publishers to notify users when the information in their web pages changes. For example, Weather.com can create a Web Slice that tells the user when a local weather update is available. eBay can deliver a Web Slice that notifies the user when the price of an auction changes. Similar in concept to RSS, Web Slices focus on updates in part of the web page, enabling publishers and users to communicate directly via the browser.

There are other markup formats that help provide context. For example, popular add-on Cooliris offers a markup format for signaling that a site contains images. By placing a bit of XML code in their home directory, site owners enable users to experience their images using the stunning 3D visualization developed by Cooliris. Another markup format, developed by AdaptiveBlue [disclosure: this is the company I founded], is called ABMeta. This format allows publishers to annotate pages that contain information about books, music, movies, wine, restaurants, stocks, and other everyday things.

All of these markup-based approaches face the same issue: publishers have to do the work of actually annotating the pages. And while the semantic web community has been very vocal about the benefits of annotation, the majority of the web is still flat HTML.

Page 2: Widgets

Widgets

In the meantime, we are seeing a surge in applications that deploy a top-down approach to inferring user context and being helpful. Instead of relying on markup in pages, these applications use heuristics and APIs to recognize the information that the user is interacting with. Based on their recognition, these smart tools then offer contextual shortcuts to the relevant bits of information. Speaking broadly, today there are two primary categories of top-down contextual applications: blog plugins and browser add-ons.

Blog plugins offering a contextual experience have been around for some time, starting with preview technologies. One of the first recent unsuccessful attempts at a preview technology was delivered by Browster. Despite its failure, its successors, CoolPreviews, SnapShots, and Apture, have done much better. While CoolPreviews literally focuses on a preview of the page, SnapShots and Apture deliver a compact summary of the information behind the link. The basic premise behind the previews is sound: if the user is not interested in what is behind the link, the preview can save the user an unnecessary click. Because the user context (in this case, the link) is known, relevant information can be brought to the surface and delivered to the user instantly.

Closely related to previews are widgets that offer contextual shortcuts. Like previews, these widgets work by being anchored to links. Examples of this technology include Yahoo! Shortcuts and SmartLinks from my company AdaptiveBlue. Instead of providing a preview of the underlying content, these technologies offer links to related content around the web. The example below shows a SmartLink on a New York Times movie page, which invites the user, for example, to buy the movie on Amazon or rent it on Netflix.

Our last example of contextual widget technology comes from Colorado-based Lijit. Lijit has developed a search technology that focuses on the individual. You claim your presence around the web, on blogs, Twitter, Flickr, etc., and then others can search your pages on specific topics. Say you are on someone's blog and want to do a search on that person; it makes the most sense to search through this person's pages first; after all, you are in this person's context.

Remarkably, Lijit offers another contextual nugget, called Re-search. It is simple, but a great example of the power of context. If you search for a term on Google and end up on a blog that has a Lijit widget, a header appears with additional results and a prompt to search for more. Lijit automatically infers your context, does a search, and offers additional helpful shortcuts.

Page 3: Browser Add-Ons and Conclusion

Browser Add-Ons

Widgets and markup technologies are making inroads into the contextual web, but an even bigger inroad is being made by browser add-ons. Since Firefox introduced its platform for delivering additional features to the browser, many thousands of browser extensions have been developed. A lot of these extension focus on enhancing the browsing experience by leveraging context. Probably the granddaddy of them all is Greasemonkey, an extension that allows users to install bits of JavaScript that alter the look and content of web pages they visit. We wrote an introduction to this popular add-on and recently followed up with a post on 7 New Greasemonkey Tweaks.

While Greasemonkey scripts are mainly regarded as experimental tools for power users, quite a few other extensions are aimed at building a business around contextual enhancements to the browser. One example is a company called WebMynd, which focuses on enhancing Google search results. WebMynd's extension automatically pushes down Google ads (clever!) to insert its contexual gadget. It allows users to simultaneously search posts on Twitter, book matches on Amazon, video matches on YouTube, and many other sources. An example of what shows up when searching for "semantic web" using the gadget is shown below.

We have mentioned Cooliris several times already. The most popular Cooliris product is the browser add-on that shows stunning 3D views of photos and videos around the web. Cooliris works contextually by automatically recognizing popular photo sites like Flickr, Google Images and Photobucket. Another contextual add-on that works by recognizing content on pages is Glue. This add-on shows you friends and other users who have visited the same book, music, movie, restaurant, wine, and other pages around the web. The context here crosses the content you are viewing with your social graph. Unlike lifestreaming applications that deliver you information about your friends out of context, Glue only brings to the surface information that is relevant to your current context.

A very different example of a contextual web add-on comes from Slovenia-based Zemanta. Its add-on makes it easy for publishers to add contextually relevant links, photos, and video to their posts. Zemanta works by applying its semantic engine to the body of the post and automatically recommending related content. Using Zemanta, bloggers are able to instantly add relevant content to their blog posts, in turn creating a relevant web experience for their users.

Our last two examples of contextual add-ons are Zentact and App Discover, both recently launched. Zentact -- developed by the folks who brought us another contextual phenomenon, MyBlogLog -- aims to solve a problem of staying in touch with people who matter to you. First, you import and tag your email contacts with different tags that reflect their interests. Then, as you browse, Zentact pops up a reminder to contact a person if it deems the page relevant based on the tags. It is a simple yet powerful example of the contextual web.

App Discover works by recommending related applications to the sites that you are visiting. Today, it requires publishers to add markup to their sites, but one can easily imagine how this technology could work top-down. The example below shows App Discover recommending TweetDeck when the user navigates to Twitter.

Browsers

Without a doubt, web browsers are in the best position to deliver the user's contextual web experience. While add-ons are taken in a variety of directions, the two dominant browsers, Internet Explorer and Firefox, have already incorporated the basic contextual experience: shortcuts. Internet Explorer 8 features technology called Accelerators.

According to Microsoft, Accelerators give you ready access to the online services you use everyday, from any page you visit. Accelerators are defined as little chunks of XML based on pre-defined variables and defined by the browser. Some examples of variables available to Accelerator are the active URL, the active domain, and selected text. The most common action that Accelerators do is perform contextual search based on the user's selection. Another common Accelerator function is the in-place lookup, such as looking up a map based on a given address.

The problem with Accelerators is that they are not really based on a selection; that is, they lack semantics. When you highlight an address, you still have to decide which Accelerator to use. If you have dozens of Accelerators installed, this quickly becomes hard to manage. Firefox has recognized the issue with the menu-driven approach and instead offers its contextual technology via text. Called Ubiquity, this contextual technology is still only available as an add-on today but is likely to be a part of Firefox core soon.

Marketed as user-generated mashups, Ubiquity is actually a contextual technology based on language. As with Accelerators, the user is able to select a piece of text and then invoke Ubiquity and type a command. In the screenshot above, Ubiquity is used to insert a map into an email. Hundreds of Ubiquity commands have been implemented to date. ReadWriteWeb has already written about Ubiquity commands.

Will Context be the Future of the Web?

So where is all of this heading? Are these technologies signal or noise? We believe we are witnessing the birth of a fundamentally new kind of web, a smarter one, a contextual one. Unlike the old web we are used to, this one understands what we are doing and helps us. It is a web in which we search less and find relevant content faster. This new contextual web is still very young and unevenly distributed, but it is definitely here.

The fact that these contextual technologies are springing up is not accidental. The Contextual web is made possible by our push into semantic web and the rise of web services/API culture. The combination of basic semantics and API is fueling all of these contextual applications. Bit by bit, the web is getting smarter, friendlier, and more enjoyable.

Web browsers are in the best position to deliver these new contextual experiences to users because of their wide reach. The fact that Microsoft made Accelerators its flagship feature for Internet Explorer 8 and that Mozilla is putting much effort into Ubiquity tells us that contexual browsing is a priority. This is really good news, because these technologies bring great benefits to the user.

It is great to see that in these tough economic times, evolution is brewing. The tremendous effort that all of these companies are making with contextual technologies is beginning to come to fruition. It may be that we are seeing glimpses of what the next generation of the web will be like.

And now, as usual, let's turn the tables. Tell us examples of your favorite contextual browsing technologies. Do you think context will be play significant part in the next evolution of the web?
