The big successes do make more money, but if you knew us you'd know that's not our top priority. The reason we want to fund the most successful founders is that they're the most fun to work with. It's exhausting trying to pep up founders who aren't really cut out for startups, whereas talking to the best founders is net energizing.

Ah, fair enough. That additional insight (along with, say, anecdotes about cases on both ends of the motivational spectrum you've encountered running YC) would be a very interesting read.

I was under the--obviously mistaken--impression that pure profit motive was involved here, and thus was curious if a blog entry would be stating the obvious. Now that you've given some more info there, I agree with my parent poster--please do a writeup!
