We recently updated communityserver.org to the latest bits. While we're not ready to call it Beta 2, we are certainly getting closer. The Beta 2 milestone is our target for being feature complete, including changes to the user interface. As such, we're busy putting final touches on features, finding/fixing bugs, and going thru much of UI with a fine-toothed comb. We're also writing samples and documentation for our new web services layer that will ship with Community Server 2008.
Now that user profiles support micro-blogging thru profile "announcements", and those announcements include support for rich content (html, images, video, ...), I'm planning on "dog-fooding" the feature and talking about many of the new features in CS 2008 from my profile. So if you're looking to hear more about what's new, you may want to visit my profile page (or just subscribe to my announcements feed). My plan is to post to it a couple times a week.
