Tonight Show staffer (with Conan, anyway) Aaron Bleyaert kept a blog and a Twitter account for the show since Conan took over last year. Of course, Jay Leno is coming back so he's no longer going to be doing the blog and wrote his last blog post when Conan's run on the show ended recently. NBC, however, took the blog post down.
But Bleyaert still had the blog post so he put it on his personal site. He talks about how Conan's last show went, what the status was on the show and Conan's future (unknown at the time), talks about the team at NBC.com, how the show will be in repeats until the Olympics, and generally says goodbye until a new show starts up. I'm not really sure what NBC saw objectionable or questionable about it, unless it's like a reader says in the comments section of Aaron's blog that they might have been upset that he linked to his personal web site and personal Facebook and Twitter accounts.
