Why should anyone ever use a Google API again?
You mean, why should you build a for-profit product while relying on someone else's not-for-profit API?I'm guessing you shouldn't!I've seen a lot of neat projects come from Google APIs, but that's as far as I'd taking it.Relying on someone else's good will for the lifeblood of your company is insane.1 exception, though:  Getting started.  I could see using Google to get off the ground and then switching to a more reliable API (read: paid for) afterwards.
