MSNBC's Keith Olbermann's crusade against Fox News' Bill O'Reilly apparently continues unabated -- though he points out that "Countdown" names three candidates a night for "worst person in the world" and "only on one occasion was it all three times Bill."

Does he ever worry, he was asked, if the "blogosphere" will take revenge, targeting him the way it targeted CBS' Dan Rather?

"There's a risk for all of us -- and by all of us I mean everybody in the world -- that the blogosphere might take revenge," quipped Olbermann (who appears not to have posted to his own Bloggermann for more than a month).

"The thing does tend to balance out," he said, noting that for every blog that dogs him, there's at least one on his side.

Plus, "very little can be said about me on the blogs that isn't true and is going to hurt me."

Postscript: I talked to Olbermann at the NBC party Saturday night and chided him for not having posted to his blog in so long.

He kind of winced and explained that his MSNBC bosses were "de-emphasizing" blogs at the moment, and that, since he wrote it on the clock, he was inclined to do the things they wanted him to do instead first.

As a union member, I understand completely, but as even a part-time blogger, I'm troubled.

Having a year-round blog, I suspect, is like having a dog. You can't just shove it in a closet and take it out only when company comes.

It needs to be walked. And God knows, it needs to be fed regularly.
