By now TechCrunch50 judges and companies know there’s no safety zone here at the conference, least of all backstage. The smart ones just run, but Google’s Bradley Horowitz is too polite for that. In this behind-the-scenes clip we talk about what exactly this Internet man of mystery does at Google, his thoughts on the cultural difference between Google and Yahoo, and how big companies can still innovate. (I’m still dubious on that one.)

We also talk about Affective Interfaces, a TC50 company that got mixed reviews from the judges this morning, but one of Horowitz’s favorites of the day.

Clip on the jump.
