What I find scary about cases like this is that nobody in the angry mob ever seems very hurt or genuinely upset - instead you see people thrilled and energized to be part of getting someone fired. If you remember the Justine Sacco thing (the woman who tweeted something before boarding a plane and went viral before landing) twitter was positively giddy about it. More than anything else it resembles the Two Minute Hate. People seem to really like having something to be righteously angry about.
