App.net at least had a couple clear use cases in mind (twitter clone, notifications/pub/sub service), even if they weren't unique/compelling enough to sell people on the service.

AFAICT, this platform has a broad scope without any kind of clear vision as to what they want to do with it. Maybe I haven't found the right part of their website yet?

Its probably not public yet. The mystery does help with marketing. Keeping people guessing is an age old tactic. Either way I'm interested.
