From what I've seen, he has demonstrated a few of the traits of a Level 5 leader (from the book Good to Great). Very humble, puts others before himself, has integrity. The fact that he's not a skilled interviewer and terrible at politics is a plus, not a negative.

The next guy to replace him could be someone that will sink the Mozilla ship.
