> probably a segment of small mid-sized businesses to prey upon making apps with this
There's a bunch of poorly run, but funded start ups, and mid sized businesses, that are literally powered by excuses. Very likely anything built with this is powering the train of excuses, not solutions. I'd go so far as to point out that Streak made it... Meaning they're obviously trying to branch out because their market isn't shit; which means, your potential market, is a segment of shit... (well as far as this site's scaling model is concerned).
If you want a lifestyle business (which I think is perfectly freakin' awesome)... sure, maybe (read: not) this is for you. But even then... it's a lot of risk for something you could probably do with one or two people. Just look at the fucking SDK changes; yeah GMail doesn't necessarily break shit, but... they (streak) do. How is that any better than your own set of brittle scripts which you have to maintain multiple times a week?
I think this is a gimmick at best, and at worst it'll completely waste someone's time and money.
