Maybe. Bit of a crapshoot between both approaches - I don't think Scott think it would blow up quite like this?
Scott is not afraid of being outed to nerds at all, but to the PC mob (sure, there's an intersection... let's replace git/master anyone?). It wouldn't especially be negative right now, but it means that his blog would be forever linked to his name. And one day is blog would attract unwanted attention (as it has in the past), and his name would be linked to it.
Also, even if wasn't for this, I think he's right to make a stand for himself. He had very little leverage here, and "deleting" the blog (it's still archived) was a bad move that makes the NYT looks bad if they go and out him.
