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?<p>I'm guessing you shouldn't!<p>I've seen a lot of neat projects come from Google APIs, but that's as far as I'd taking it.<p>Relying on someone else's good will for the lifeblood of your company is insane.<p>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.
