Many new technologies work best in concert; the functionality of one application can be vastly improved by using it together with another one. Here are some of our favorite examples of apps that work best together, followed by some favorite workflows from friends of ReadWriteWeb. We hope you'll share your favorite combos in comments, too, so we can all learn some new things.

AideRSS plus Snacker

RSS news ticker Snackr was an app that people either loved or hated when we first wrote about it here. The attractive Adobe AIR interface is now even more compelling now that you can sync it with your Google Reader account (as of last week). One of the best uses we've found for this ever-flowing stream of news though has been to fill it up with "best of" feeds from AideRSS. AideRSS is an app we've written about over and over again here because it's just so darned useful and cool.

Put the two together though and you've got a stream of just the breakout hits from high traffic feeds. We enjoy and recommend reading the top stories on topics like the semantic web, mobile and recommendation technology through Snackr - but we're sure you can build your own easily.

Ma.gnolia (or Del.icio.us) plus Feed.Informer

You can do a whole lot of different things with social bookmarking tools like Ma.gnolia and Del.icio.us, probably including some things most readers here aren't familiar with. One of our favorite things though is to pick a particular tag from your account and run the RSS feed from that tag through a handy little service called Feed.informer.

You can display any amount of the feed on a web page with just a few lines of embed code, including the "notes" field for your tag as editorial or summary information. The result is a little news section for your website, powered by your social bookmarking tool. It's a great way to continue sharing found items online that don't warrant an entire blog post.

FriendFeed and MuxTape plus FluidApp

We wrote here earlier this year about a fabulous mashup of mixtape service Muxtape and single-app browser creation tool for Mac called FluidApp, but it's also really useful to combine FriendFeed and Fluid.

Most of the other standalone FriendFeed apps are hard to use (excluding the wonderful mobile app FFtoGo) but putting your friends' feeds and conversation in a standalone browser makes it easy to follow along without losing the FF tab in your browser. FriendFeed's auto-updating keeps the dedicated browser up to date and the FF favicon looks great in your dock.

Single app browsers fall into the "seems stupid until you try it" category, but put the right app in there and you'll enjoy it.

Windows users can check out Bubbles, a service that was reviewed and discussed recently at Download Squad.

Facebook plus Dapper

The RSS extraction tool Dapper is really powerful, once you figure out how and why to use it. Here's a 4 minute screencast we recorded about how to use Dapper but the sky's the limit with what you can do with this free tool.

One of the things we've done with it lately is scrape birthday notifications out of Facebook. Not everyone logs into Facebook everyday, but people tend to put their real birthdays into their profiles there. It's really nice to get those birthday notifications by RSS in another setting that you spend time in more regularly. Step by step instructions for doing so are available here.

Friends of RWW

We asked around and got some input from friends about what apps they like to use together. The responses ranged from combinations aimed to increase productivity to making the most of music listening. Here are some of our favorites.

Local Portland tech blogger Rick Turoczy says he likes to use Twitter search (formerly Summize), combined with Yahoo! Pipes and RSS to SMS service Pingie. We're not sure what he does with those apps together, but the magic results in his getting a lot of industry news before mainstream media outlets do.

MicroISV consultant Bob Walsh makes the most of his fleeting thoughts by sending voice recordings through Jott over to "memory extender" EverNote and "thence to various programs on my Mac." That's the kind of thing many of us have probably envisioned doing, we're glad it's working for Bob.

Susan Kirkpatrick (no relation) is a prolific multi-media blogger. How does she do it? [I] "send a blog post with a picture attachment via email to Utterz; it posts to Flickr, WordPress, Pownce and Twitter." We haven't used it a lot ourselves, but Utterz is pretty impressive and we here rumors that there is even more sophisticated developments being worked on behind the scenes there, too.

Virginie De Bel Air says she likes Last.fm + SonicLiving, a service that tracks your favorites on iTunes, Last.fm or Pandora and notifies you when those bands are coming to perform in your area. Utilitarian and rock and roll! We hadn't seen SonicLiving before.

Security and IT exec Greg Hughes likes to let his hair down and shout Shazam! sometimes. Specifically, Hughes says he finds himself using the Shazam music identification app to identify a song he hears and then Pandora to discover more that's related. All on the iPhone, too.

What About You?

What are your favorite apps to use together? There are so many new apps that launch everyday, we can't imagine the infinite permutations that users could come up with. Putting together multiple apps usually implies though that you're fairly comfortable with one or both of them, that they are equipped to live as something other than a walled garden and that each has stood enough of a test for users to believe they are stable enough to smoosh together.

Productivity? Fun? A combination of both, perhaps? We'd love to know what your favorite apps are to run together.

Google Gears Turns One: Future is in Open Standards

Google Gears, the offline web application API it debuted last year at its developer conference, turned one this week. To celebrate, Google dropped the company name from Gears. The name change is a symbolic move aimed at reinforcing Google's commitment to working with existing standards communities and helping them to define better open standards for bridging online applications and the offline world.

The Ultimate Yahoo! Pipes Creations List

Yahoo! Pipes is one of the coolest ways to mashup the RSS feeds of various sites and sources to get the data you want. Since our initial coverage of Yahoo! Pipes, thousands of creations are now available. However, finding the best picks can be tough. ReadWriteWeb has done the hardest part and comprised a list of some of the best Yahoo Pipes created by users. We give you the ultimate Yahoo! Pipes list.

Strands Lifestreaming: What They're Doing and Invites for Readers

Recommendation service Strands.com launched a lifestreaming service this week that aims to pull together the company's wide range of services in particular media and online activity into one central place for users to share socially. The new Strands is a way to share your music, bookmarks, blog posts and other activity with friends, family and groups. It's a major entry into one of the most interesting sectors of the new web. We give it a mixed review...

Semantic Tagging with Faviki

Faviki is a new social bookmarking tool that offers something that services like Ma.gnolia, del.icio.us, and Diigo do not - semantic tagging capabilities. What this means is that instead of having users haphazardly entering in tags to describe the links they save, Faviki will suggest tags to be used instead. However, unlike other services, Faviki's suggestions don't just come from a community of users and their tagging history, but from structured information extracted straight out of the Wikipedia database.

Freebase: Dispelling The Skepticism

Freebase, the first product of semantic web company Metaweb, is an open, semantically marked up database of information that we called one of the "10 semantic apps to watch" last year. With $57.4 million in funding, a smart team, and a tech legend in Danny Hillis at the helm, Metaweb is considered to be one of the most serious players in the Semantic Web space. Yet the company's efforts to date have been met with skepticism. Particularly, people have asked how is Freebase different to Wikipedia? Jamie Taylor, the Minister of Information at Metaweb, spoke at the SemTech 2008 Conference that took place in San Jose last week in an effort to dispel some of that skepticism.

Semantic Search: The Myth and Reality

For a few years now people have been talking about semantic search. Any technology that stands a chance to dethrone Google is of great interest to all of us, particularly one that takes advantage of long-awaited and much-hyped semantic technologies. But no matter how much progress has been made, most of us are still underwhelmed by the results. In head-to-head comparisons with Google, the results have not come out much different. What are we doing wrong?

Android Is Out For iPhone Blood

Wednesday, at Google's I/O Event, the company demonstrated their Android prototype phone, a device which has been greatly improved since its last public outing at this year's CES and Mobile World conferences. Today, Android looks classy enough that you half-expected them to pull a Steve Jobs and announce that you could run out and buy it right now. During the demo, the company showed off some of the applications that will run on Android - like a Google Maps Street View app that drew cheers from the crowd. From the buzz surrounding the Google Phone at this event, it's clear that Android has a shot at knocking that other touchscreen phone off its pedestal.

The Social Networking Arms Race

Last November, when Google launched Open Social we asked readers if Facebook would join Google's platform. The results were split right down the middle, but as we get farther from the Open Social launch, and the two sites continue to launch competing APIs (Google FriendConnect vs. Facebook Connect, for example -- the former banned by Facebook), that seems less and less likely. This is becoming a social networking cold war.

The Fork in the Road for Social Media

Social networking is at a major fork in the road. Down one road is adding more features to a walled garden and opening up just enough, so that users seldom need to leave. Most sites are going down this yellow brick road and the prize is clearly a big one. But they may end up back in Kansas. Down the other road, lies a future of being the primary repository for your connections (aka the social graph), but with this data available via open APIs to anybody who needs it. That is a utility type model, and as with any utility, it can be hugely valuable at scale.

Who Are The "Digitally Savvy?"

A new report put about by consumer and media research firm Scarborough Research has revealed some interesting information about the section of the U.S. population that's being called the "digitally savvy." These are the consumers who are more likely to own high-tech items like DVRs, satellite radios, and VoIP phones and are more likely to engage in Internet activities that include blogging, downloading music, and other web 2.0 activities. In other words - they're us.

Did We Miss Something

Yahoo! Pipes is the first GUI builder for the biggest database in the world, the Web itself. This list is far from complete, but it's comprised of the best Yahoo! Pipes creations available. If you have a creation or know of one that didn't make the list, leave a comment down below and we'll be sure to review it to keep growing our list.

One thing Pipes has not done before today is offer a way to display updated data automatically on another web page. That has finally changed with the release of some javascript badges from the Pipes team. They are nice, but they aren't really good enough, to be honest.

The second badge type is the geotagged photos badge. I'll be damned if I can filter Flickr by geotag in Pipes, no matter what I put in the the location field it doesn't work for me. Maybe you're smarter than me though and will appreciate this feature.

The final badge type is the slideshow badge, again displaying Flickr images.

What's wrong with these badges?

I display RSS feeds on web pages all the time, I love it. I use a great service called FeedDigest. Unfortunately, since its recent acquisition by a large Russian software company FeedDigest hasn't been very hospitable to new users. None the less, I use it all the time in important situations. I pay more than a hundred dollars a year for premium capacity there and I pay it happily. Yahoo! Pipes is really useful too - it's in the same class as Dapper and AideRSS in terms of usefulness, maybe even more useful albeit less easy to use.

For the more code savvy, MagpieRSS on your own server is the way to go. The idea behind these tools, though, is that they let progressively less technical people do progressively more powerful things. It's in that way that the Pipes team dropped the ball with these badges.

Why are the new Pipes badges suitable only in a pinch, or in inconsequential situations? First, contrary to what Yahoo's Jeremy Zawodney says in the demo video embedded below, these badges are not particularly customizable at all. They are a single line of javascript with one or two drop downs or fields to define traits like height and width. Perhaps heavier customization could be done with a lot of elbow grease and the Pipes backend, but for all intents and purposes these badges are uncustomizable. App vendors should stop calling skinnable displays "customizable" because a growing class of self-publishers wants much more. That's the case in the video publishing world and that's the case here.

Second, the output is via javascript, so it's invisible to search engines. Other alternatives provide PHP code to add to a page. You can do serious processing with Pipes, so why don't these badges enable you to finish a serious job?

I would love for Yahoo to provide real customization and search engine visible PHP output. That's my ambivalent but interested take on this announcement, let's look at the happy faces of Yahoo! folks showing us how it works.

Feed Rinse is a best of class RSS filtering application. It offers filtering by keyword, tag, author, title, etc. It supports regular expressions, has a built in profanity filter, and lets you upload your OPML file for easy importing of your RSS feeds (it can also export to OPML). And since we first covered it in April of 2006 it has gone completely free.

FilterMyRSS is a no-nonsense keyword filter that filters posts out by keyword. By that we mean that the service tracks posts for the keywords you want to filter and removes posts where it finds matches. It can filter by description, title, or category and offers some advanced XML options.

When we first reviewed 2or3things' Blastfeed in late 2006 it appeared to be shaping up as a good consumer filtering alternative to Feed Rinse. But since, the company has shifted gears and now offers Blastfeed as an enterprise filtering solution. Blastfeed's keyword filters can also be used to remix and republish blog feeds filtered for specific content -- for example, a fan site for a specific band could create a news feed from multiple general music sites that publishes only stories about that specific band.

Feed Sifter is an almost painfully simple RSS filter that filters in by keyword. Or, in other words, it watches for the keywords you enter and pushes stories to you that match those keywords. It can search for single keywords, or return stories that only match sets of keywords.

ZapTXT is a keyword filter (of the in variety) that returns results via email, instant messenger, or mobile phone. It is designed for people who prefer to consume RSS feeds via non-traditional methods (i.e., not via an RSS reader). ZapTXT also powers email, IM, and SMS alerts for sites like TheStreet.com.

For do-it-yourselfers, Yahoo! Pipes offers an easy way to create filtered RSS feeds. The RSS remixing application makes it easy to create simple filters. Just define your feed using the "Fetch Feed" module, connect it to a "Filter" module, which can filter either in or out by title, description, category, author, or date, and then connect it out to the Pipe Output. It isn't as comprehensive as Feed Rinse, but you do perhaps have more control. The example pipe below would filter our feed and return only posts that talk about "Facebook" in the title.
