Just registered for the anti-Twitter. You can follow me at jimwitness. What is Twatter?? Here’s a blub taken from their About page.
Twatter is a micro-blogging service based on the Free Software StatusNet tool.
If you register for an account, you can post small (140 chars or less) text notices about yourself, where you are, what you’re doing, or practically anything you want. You can also subscribe to the notices of your friends, or other people you’re interested in, and follow them on the Web or in an RSS feed.
