Get wiki with it. The Supernova Wiki is now up and running, courtesy of my friends at Socialtext.
What's a wiki? you ask. (Or at least, some of you ask.) It's like a collaborative Website where each page is editable by users. The wiki is useful for real-time information and collaborative tasks (like figuring out where to meet for dinner) that don't work as well with the linear narrative structure of Weblogs.
The Supernova wiki, like the group blog, is open now for your contributions. [Werblog]
