The Facebook integration is pretty unnecessary, and the entire site is totally unactionable. I see no data here, and I can't actually accomplish anything directly through the application. What is this supposed to do again?
Exploit the competitive nature of San Francisco residents to collect a huge slab of facebook user details which can then be targeted for direct marketing? Just, y'know, at a guess...
Cool idea, but I would appreciate notification that it posts to my facebook wall.
Does this accomplish anything other than filling up my facebook feed with pointless "Like"s?
