In honor of Mr. Looking Out for Us, whose tactics this move emulates, here's the ridiculous item of the day:

Donald Luskin had an attorney send a letter to Atrios threatening to take legal action if the latter doesn't remove some allegedly libelous posts and comments from his website. Apparently, Luskin has yet to identify the offending comments; he wants all comments removed.

Suffice it to say this kind of maneuver, even if unsuccessful, has a chilling effect on the blogosphere.

There's already a fair level of commentary up on this, and, I'm sure, plenty more to come.
