Per Michael Arrington’s request I ran backstage and shoved a camera in CitySourced’s founders’ faces just after they completed what was one of the more compelling presentations of the day.

Question one: Palm is really paying companies to write apps for the Pre? Yes. How much? All I got despite truly obnoxious questioning was “under $500,000.” (If you’re a developer and you have a better answer, leave it in the comments or send to tips@techcrunch.com.)

We also talked about the biggest execution risk: Whether or not cities will actually use this data to make citizen’s lives better? Gavin Newsom: I hope you’re paying attention to this.

Video is on the jump. (Sorry for the jumpy camera work. It’s still early here.)
