I don't want to get into the nerd vs geek debate here but my interpretation of TFA was that it was specifically talking about the types of people that simply didn't want to play the social hierarchy game. Just being interested in and doing nerdy/geeky things does not place you in that group (unfortunately the terminology we have does a poor job of distinguishing this).

I also don't think there is any implication that I want an abrasive culture. I do not think that early google style corporate culture is a good thing. I think we need to dissociate nerds behaving badly from simply not picking up on social signals or not caring about them. The reason I say this is because when you treat someone as a villain who is simply thinking out loud you basically stop any potential for real dialogue in its tracks.
