Reaction to MSNBC anchor Keith Olbermann naming CBS Evening News anchor Katie Couric "Worst Person in the World" Tuesday night continues across the blogosphere. Olbermann has now called out Huffington Post media editor Rachel Sklar for her criticism of him. It comes in the wake of this post Sklar wrote yesterday.

In the comments section of a Daily Kos blog post he wrote, Olbermann responded to a commenter who questioned Sklar's criticism of MSNBC and Olbermann. Sklar "has it in for you big time," wrote the commenter. Olbermann responds:

Don't know what to think about Ms. Sklar. Actually, I'm mildly alarmed, but not because of the criticism. She — let me phrase this gently — attended the Countdown 5th Anniversary Party in April, even though she had been denied an invitation and was not accompanying a guest.

But Sklar tells TVNewser, "Keith is mistaken. I'm sorry he was alarmed, but I was not at the event."

And this isn't the first time Sklar has taken on Olbermann...

• In April, Sklar wrote about Olbermann suggesting Sen. Hillary Clinton should be beaten, when he said, "Somebody who can take her into a room and only he comes out."

Calling it "much worse than Pimp-gate," she wrote, "I don't think that Olbermann meant it literally, but that's not the point. Words matter, and so do the images they evoke. This can't be ignored."

Olbermann didn't ignore it — he issued a written apology and did so on the air as well, although as part of his apology to Sklar he wrote, "You could've called for reaction first if your main motive had merely been criticism."

• In October 2006, Sklar named Olbermann, "today's worst person in the world," for using the chyron, "A Slut and Battery," regarding a Paris Hilton segment.
