Thursday night on MSNBC's "Countdown," Keith Olbermann announced that he has joined Twitter and sent off his first tweet.
"I give up. I was wrong. Young and foolish. Now my twitter-cot belongs to the ages. Behold: I tweet," his first tweet read.
Olbermann, who will tweet at @KeithOlbermann, already blogs at both MLBlogs and Daily Kos, but had resisted Twitter before Thursday night.
"Late in the summer of 2008, I even signed up for Twitter. Then I suddenly thought, 'I think I might accidentally give a bunch of people my e-mail address.' So I blinked...but adjustment is life," he said.
"I always thought people were following me, so why add technology to paranoia?" he joked.

By Friday morning, Olbermann had over 18,000 followers.
Last year, Olbermann actually named Twitter the Worst Person in the World for allowing a fake account under his name to amass thousands of followers.
