Has anonymous commenting destroyed meaningful online dialogue? This guy thinks so -what do you think? I now get far less email overall than I used to, either positive or negative. You already know the reason: Anonymous commenting. Those semi-public forums like the one you see right down there, at the bottom of this very column, those "community" discussion areas borne of the blogosphere and spread to every media site imaginable, from SFGate to the New York Times to YouTube to Knitting World. Indeed, they're one of the most popular, widely used innovations of the Web 2.0 revolution, and they've dramatically transformed public communication and conversation. For the worse. Oh, for the far, far worse.
