Just asking

With the explosion of blogs on the Web, and the emergence of premiere blogger celebrities (bringing you all the latest news, gossip and partisan political bomb-throwing), it makes me wonder when these amateur sleuths and journalistas are gonna get tagged with a slander lawsuit. I've seen some pretty incendiary things on different islands in the blogosphere, and (Michael Savage's idiotic thin-skinned litigation, notwithstanding) I'm just curious when the blogs are going to come of age and join newspapers, radio and television in rules governing what you can't legally get away with under the guise of free speech.

Namely, when is someone major like Instapundit or Atrios going to get dragged into court for something they posted?
