As a child, the standard cry whenever you lose something is “who stole my pencil?” (or whatever). To a child, it doesn’t occur that he simply forgot where he left it, it must be the fault of some malicious external actor.
Keith Olbermann, it seems, never grew up. Olbermann blasted Twitter as the “worst person in the world” when he learned that it had allowed someone else to open a Twitter account in his name. That someone naturally had to be Fox News. (Those guys are always stealing Olbermann’s pencils.)
As it turned out, the Twitter account was being run by Olbermann’s employer, MSNBC, which was running it to promote his program.
