seeing as how there are, in this very thead, people that consider OP to have been a dickhead, i think i'm going to go with the primary source on this one.
Considering how the OP is the mythical 10x-100x programmer, I'd lean towards him not being a dickhead. He singlehandedly implemented several key features for FaceBook. If FaceBook had an average employee instead of the OP, they might not have been as successful.
This is why the 10x mythologizing is so annoying. There are a few people who are 10x in specific areas or who might have periods of intense productivity but it's never true across the board for significant periods of time, and it's used to excuse a lot of bad behaviour by 1.2x programmers — not to mention the larger mistake of assuming that the limiting factor on projects is rarely absolute programming ability. In most cases, you see far better results from someone who might be maligned as a .8x programmer who communicates well with the team & users and relies on solid tools and practice rather than assuming sheer skill will save the day.
