Tell your family, tell your friends, Chatsum has gone open beta and now absolutely anybody can join in for free.

We’ve had a great response from our closed beta testers who’ve been nagging us to open it up for everyone so that’s exactly what we’ve done. Please bear in mind this is still a beta and currently only available for Firefox. Bandwidth charges permitting we’re now getting to work on adding more features and support for more browsers.

Visit this page, fill out the form, get using Chatsum and let us know what you think.

Today we’re releasing some hot new Chatsum features, and for the first time, they’re not just for beta testers! We have just rolled out our Chatsum user profile pages which can be viewed by anyone. Check out mine:

Every Chatsum user now has the ability to publish their browsing history, weekly and overall top sites, not just has a profile page but as RSS too! We’re also encouraging users to plug-in their feeds from other services like Flickr, YouTube, Digg, Del.icio.us, Last.fm, Upcoming, etc. so you can see all of these feeds in one place. Check out Lee’s profile:

You can keep an eye on who’s been online and edited their profile or search through the current member list here:

In order to test these new features fully we’ve also invited in the 1500 users who were waiting for the next round of beta testing. If all goes well and there are no major bugs found, we hope to open Chatsum up to anyone in about a week.

Please let us know if you find any bugs here: Known bugs

Pictured left is another way of viewing the Chatsum dataset that we’ve been playing with here in the lab (Click the image for the fullsize version over at Flickr.com). Each favicon represents a unique web address added to the database of visited urls. The timeline reads left to right, top to bottom.

Obviously this is only a small subset of the data but it’s great to start interrogating it from a visual, rather than textual, perspective. Once we’ve made it a bit more user (and server) friendly we’ll let you have a go!

P.S. For everyone wondering what the Chatsum 0.6 update brought - I’m afraid it was only Firefox 2.0 compatibility for all the early adopters. We have, however, made serious progress with the new features we’re planning to roll out soon so keep your eyes peeled for more updates from us in the coming weeks.
