One of the things I know people like about Twitter is that some famous people have started using it too. While some may not care if their co-worker is walking her dog, they might be interested to read a Twitter message from Paris Hilton walking her dog. Or paying someone to walk it, perhaps.

There’s even been some recent news about star athletes using Twitter — Charlie Villanueva, a forward for the NBA’s Milwaukee Bucks, made news for posting to Twitter during halftime of a game on March 15, AP writer Chris Jenkins wrote a few days later. Villanueva was later asked by his team to refrain from using the service during games. Howard Beck of The New York Times reported that Phoenix Suns center Shaquille O’Neal recently started using Twitter after a 33-year-old fan named Ward Andrews was discovered impersonating O’Neal.
