I use the same google Id, but I've (attempted) to remove the identifying info from my profile on Programmers. Can it still be correlated with my SO identity? (by random people, obviously SO staff could) Or another way to ask the question is, who am I?
Since SO is theoretically an extension to my future resume, I'd rather not have my identity there associated with my identity on programmers.stackexchange.com, which in my opinion, is where the argumentative, combative and other bad-behavior-encouraging questions end up.
I suppose if one doesn't want to get into a bar fight, don't go to bars, but on the other hand, sitting out the discussion isn't an attractive option either.
