Writeboard, the latest web service from 37signals, is now live. Think of Writeboard as a web-based whiteboard that can save all of your edits as you share with other users, and you can use Writeboard solo, too. Backpack users can attach writeboards to their backpack pages. The Writeboard web service is completely free. I'm definitely going to look in to this more, as I agree with the 37signals gang: "Wikis are icky."
