Congrats Keith :D
I've met Keith a few weeks ago at the NodeJS NYC meetup. Great dude, who genuinely wants to make development better. Polybit seems particularly cool for front-end / designers, mobile devs, and anyone else who'd rather build an app than fret over the high availability, scalability, or etc.
What I'm saying is: cool idea + Keith's very approachable if ya wanna pick his brain about the design :)
Hope this goes well for ya dude!
