This app has always made me feel a little stupid -- what's the use case? I get the SDK use cases (e.g., for a dieting app or a library cataloger), but is the main app a marketing vehicle for the SDK and a "check this out, gee whiz!" kind of thing? Those are valid purposes, I'm just wondering if I'm missing something. Don't get me wrong -- the technology is super cool, but I remain confused. (Congrats to the team on the acquisition.)
