Wil Wheaton (actor, ubergeek)

Yes, @wilw was in Star Trek: The Next Generation and Stand by Me, but he’s now spent far more time as a high-profile nerd than as one of America’s favorite child stars: Anyone who spent time as a programmer on Newtek’s Video Toaster has all the geek street cred he’ll ever need. And the man is a tweeting machine: Yesterday, he tweeted about his lunch (green tea and rice), the deaths of Patrick McGoohan and Ricardo Montalban, soccer, Roku’s streaming-movie box, and the fact he thought it was Tuesday even though it was really Wednesday, among other topics.
