Here are the latest tools and services we've come to love, maybe you'd like to give them a try too.

Think you find a lot of great stuff online? You should try sharing it with people using Posterous. The user experience for this curation and blogging tool is remarkable, a real model for other app makers to check out. Posting by email, iPhone and a web bookmarklet are all really easy. My Posterous is here and Frederic Lardinois shares some of this favorite stuff here. If you like what we write about on ReadWriteWeb then check out the cool little things we find but don't blog about at the day job - or the things that will make it to ReadWriteWeb later. Posterous just went real time this week, too.

Topify

Ever feel frustrated by the emails you get from Twitter? We did, until we signed up for Topify. From really smart "X is now following you" emails to the ability to reply to direct messages by email - Topify delivers Twitter emails like Twitter ought to. It's another project from Ouriel Ohayon, who's also behind the wonderful iPhone app sharing service AppsFire. Ouriel makes cool stuff.

Seesmic Web

The never-ending battle between Seesmic and Tweetdeck to see who can make the coolest Twitter client is great for users. Tweetdeck ate my groups last night in an upgrade, after I'd spent hours building them, and so I decided to give Seesmic another try. The Seesmic Web app is awesome and Mac users can turn it into its own app on the desktop using Fluid. The best of many cool features? List support! You can turn any list you're following on Twitter into its own column in Seesmic. Frederic Lardinois says he's been using this combo for a few weeks, I still have some kinks to work out.

Tweetie 2

The iPhone app Tweetie (iTunes link) made a major upgrade last month and we're loving it. Sarah Perez put this one on the list but everyone agrees - this is hot stuff. Will the forthcoming Seesmic Mobile app be as good? Will Tweetdeck's eventual support for Twitter lists turn into an awesome iPhone app? We'll see - but Tweetie's many rich features make it the app to beat right now. My favorite feature? The way the replies page can be pulled down like a spring to prompt a refresh. It's a little thing, but it's fun.

Aardvark

Aardvark leverages what it calls "the real-time web of people" to deliver answers to any question you have - from people in your social circle who know about the topic and are available at that very moment. Vark gets mixed reviews from some people, but I love it. From technical questions to practical ones about life to opinions about questions I have at work - I've been getting a lot of fast, helpful information from people on Aardvark lately. It's another app that scores very high on User Experience, especially in its iPhone and IM interfaces.

Chrome/Chromium

Google's web browser is fast, it's really fast. It's hard to say goodbye to all the wonderful Firefox extensions we've been using for years - but it's harder to use any other browser once you've been using Chrome for awhile. We have high hopes for Chrome plug-ins, but even without them it's a joy to use. You can download Chrome for Windows here and Chromium for Mac here.

LazyFeed

LazyFeed is a topic-driven "discovery engine." It's basically a blog search client that brings in the freshest posts about topics you're interested in. A couple of months into using it, I'm still finding great content every time I fire it up. I've got this running in Fluid and it works great.

Want some serendipity on the iPhone? Try out competitor YourVersion's app. The first version isn't easy on the eyes, but it delivers roughly the same experience on the go.

Cruz lets you easily set up multiple panes in your browser, with sophisticated controls. That's just one of the many things it does, but it's the feature we like best.

In addition to the multiple panes, Cruz also offers a full-screen mode and a long list of other features.

We really like the idea of being able to set up any web app we like as a sidebar. We tested it with FriendFeed, setting Cruz to act as an iPhone in that panel. It worked pretty well, though the status bar's ability to preview URLs was lost.

We also like the idea of of side-by-side browsing, as we often like to compare two web pages at a time or drag text from one to another, and using two browser windows is less handy. Unfortunately, there's no ability to bulk-import bookmarks from another browser, something we'd want to do before using Cruz too extensively.

Finally, we wish we could run separate Google Accounts in this browser and in Firefox, simultaneously. Unfortunately, that's not possible with Cruz any more than it is with Fluid.

Despite its early shortcomings, Cruz is fun to use. We expect to fire it up in some circumstances and we wouldn't be surprised if it suits some people well all the time. Three cheers for innovation in the world of browsers!

Thanks to Chris Messina for discovering this, as he does so many things.

The improvement in user experience for this already fantastic app is remarkable. Check out the how-to video embedded below. It's also a great example of several brand new apps all put to use together.

You can also skip the Fluid part and just download the completed "app" from Tom Martin's blog. You'll still have to make the CSS edit yourself, though.

If you've wondered why you'd use Fluid to make a standalone browser for a single web site, this is a great example. Following Sproule's instructions was remarkably easy, it took me less than five minutes and added a wrinkle to my internet experience that I expect to use regularly.

I struggled for awhile until I realized that my Mac needed a software update and that solved the problem of previews not appearing right away. For some reason still, a couple of the pages aren't fully previewing - but this is a much better experience than the standard Muxtape black box.

This really inspires me to try some more things out with Fluid, including perhaps a standalone FriendFeed browser - since the newly released AlertThingy really aint doing it for me. Update: While walking my dog and listening to Newsgang talk about politics and Twitter, I realized that to be honest it was through AlertThingy that I saw a Growl popup about Engtech Digging Sproule's post about this. Sometimes I drown in a soup of input and forget exactly where I first find things. I apologize for that.

The Coverflow feature combined with Muxtape is really great though.
