I guess I'm not hip or social enough to get it. It's like a glorified e-mail/IM client with avatars and social networking stuff, and a bunch of other things super glued to it? Seems like it might be too ambitious. Maybe there's a good idea in there somewhere but, looking at the tools/sites I use now, I can't imagine why I would want to use this instead. I certainly don't want to waste my time duplicating my efforts on more than one site/service/whatever. Looks like there might be a decent barrier of entry too just figuring out how all these parts work with each other and how you can modify them to work the way you want them to.
