There's a placeholder page at BuddyPress.com right now, with the Automattic logo and a simple description of what BuddyPress does: transforming "a vanilla installation of WordPress MU into a social network platform." For an example of what that might look like, you can check out Peatling's work on chickspeak.com, built on BuddyPress. If you're a designer who likes the power and flexibility of WordPress, but you need to get outside the basic blog and put together a full-on social network, user profiles and all, this could be a great solution.
