If you post, check fine print

Dane Cook just breathed a sigh of relief after reading Twitter's latest user agreement, which does not claim ownership of his or anyone else's Twitter posts. He may or may not use such posts in a future book, he says.

For a while, the comedian -- who built his first national fan base online and who has 1.3 million Twitter followers -- had reason to worry.

"There was that whole thing with MySpace and Facebook, where it was like: 'Everything you do here we own -- every picture, every item -- we own. We can make a commercial with it, we can build a TV show with it.'

"That was very scary. Always read the fine print," says Cook, who does stand-up Saturday at Andre Agassi's Grand Slam for Children.

MySpace now clearly says in its user agreement that it claims no ownership of your posts: "MySpace.com does not claim any ownership rights in the text, files, images, photos, video, sounds."

Facebook execs say that Facebook doesn't claim to own user content and that we shouldn't worry about this confusing language in its user agreement: "You grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook."

Whatever. I just changed my Facebook privacy settings to try to jump out of that loophole. Paranoia will destroy ya, but it also protects intellectual property rights.

As for Agassi's good-hearted charity event at Wynn Las Vegas, Cook is joined by Tim McGraw, Daughtry, Brian McKnight and Lionel Richie. You can't buy normal tickets. Merely buy a table for $17,500 to $85,000, or a couple of seats for $3,000 to $8,000. Browse or donate at AgassiFoundation.org.
