Corey did take a lot of time to apologize again and again on Twitter. I think he dealt with the situation quite well, considering the douchiness he (and the others) exhibited.
No kidding -- I checked his twitter stream to see what this looked like, and stopped scrolling after a few pages of nothing but apologies.
Sucks to make these kinds of mistakes; I've been thoughtlessly cruel before in my life (though never with the amazing and horrible amplification that the internet provides, thank goodness), and it's a nasty feeling indeed when it all sinks in.
