Actually, the guy seemed more like a manager/business type than a hacker. The first thing I asked him was "are you spying for Google", and he hemmed and hawed actually. He gave no indication at all that he was interested in doing a startup himself, but wanted to figure out what we were doing.
Google doesn't have managers! Everyone there is 10 feet tall, types 200 words a minute, codes in a new version of Lisp called GLisp and can beat up Chuck Norris. You must have been mistaken.
