Twitter is everywhere. Public figures from Perez Hilton to John McCain and Lilly Allen to P. Diddy are using the site to update their status in 140 characters or less. Most recently, Lindsay was caught drunkenly commenting on the emotional roller coaster that is her love life. But some stars, like Paul Rudd and Rashida Jones, have decided that Twitter is not for them.

“I’m afraid of the Internet. I’m too old to tweet,” said Paul Rudd when E! News caught up with the stars of I Love You, Man at Austin’s South by Southwest Film Festival. “So I don’t tweet, I tw-t.”

“If I didn’t talk to you in high school, I don’t need to talk to you you now,” agrees costar Jason Segal.

And while some stars will tweet their exact location and invite fans to rub up against them at a bus stop, Office vixen Rashida Jones isn’t so hot on the idea, “I don’t need to invite stalkers into my life. I just don’t really see the point.”

This could be part of a growing trend among celebs who were stung by the Twitter bug.

P. Diddy, who has been known to twitter about tantric sex and raucous parties, recently switched his Twitter to private, which means that only 107,356 of his followers will know when Diddy decides to party till 6 in the morn’ or stay home and floss.

However, one high-profile Tweeter has become one bona-fide member of the Twitterati, actor and Iron Man 2 director Jon Favreau. At a panel discussion for Rudd and Segal’s movie, titled “I Love You, Man: Are You Saying it Enough?”, Favreau applauded Twitter as a “grassroots” way to reach out to fans and generate word-of-mouth buzz for smaller movies.

Favreau live-twittered the event and even snapped pics of his tweet-shy costars Rashida and Jason, proving that the social-networking tool-cum-promotion machine may be here to stay, whether celebs like it or not.

It’s appropriate that Rashida Jones and Paul Rudd choose not to tweet. Although they’re celebrities, they tend to be private and don’t feel the need to keep the public updated on their every move. Twittering is perfect for celebrities who want constant coverage (think Lilly Allen and Lindsay Lohan), and public figures who want to stay relevant. Even more than Facebook, Twitter allows attention-starved celebrities to keep the public updated on their every move. The length of the posts and the topics they tend to discuss (Lilly Allen, for example, recently updated on her consumption of ribs in bed), makes the audience feel like they’re getting a text message from the celebrity. Too bad Obama hasn’t updated his Twitter - it would be fun getting texts from the President.
