Bob Garfield tells On the Media listeners what he really thinks about the "frustrating, maddening and extremely discouraging" online feedback he often receives from anonymous commenters and gets an earful from Ira Glass. Then, the social media consultant and blogger Derek Powazek weighs in: "Comments online are just like conversations in newsrooms - sloppy and stupid and often wrong. But they’re the raw stuff that great journalism starts from."
