Would you prefer advice from a socially incompetent developer?
If I'm at point A and want to reach point B, I'd value advice from someone who went A->B (and now comfortably sitting at B) more than from someone who is still stuck in A with me.
Perhaps. If one is a socially incompetent developer, it's quite possible that one might find advice from another socially incompetent developer to be more relevant and actionable than advice from a socially competent developer.
Assuming he went from socially incompetent to socially competent. Patio11 seems very much like he is more naturally gifted than the [stereo]typical developer in this respect.
If you go through his blog you'll find that he was a very shy engineer himself who couldn't look people into the eye. I guess we should all understand that there are only very few things / skills that can't be learned.
Did you come out of the womb knowing how to program or is it something that you spent some time on, reading, practicing, working your way through uncomfortable situations?
Social competency is a skill just like any other and requires practice and learning.
