Just finished watching this talk. Its pretty good. My only complaint is that there seemed to be a lot of generalization and non-technical flavor despite the technical audience (unless I'm misunderstanding the purpose of Google Tech Talks). I would have like to see him cut about 30 minutes off this presentation or fill it more with examples and case studies.
Thanks for the feedback. I think I have a little too much material in the talk for the format. The same slides took me 2 hours to get through at a user group meeting that night. My next goal is to cut the talk in half. Maybe 2 talks, one on the API, and another on the use cases.
