It's a great week for John Hodgman fans. Hodgman -- you know, "The Daily Show" expert, the guy who plays the PC in Mac ads. He is suddenly everywhere: back on Jon Stewart's show last night, talking to "Rachel Maddow" on Monday night, guest blogging on BoingBoing, Twittering about the presidential race, showing up in some new Mac/PC ads out, making appearances in New York, various blogs and podcasts. It's all about promoting his new book, "More Information Than You Require," officially released Tuesday. By the way, if we are heading for another Great Depression, we're going to need more than 700 hobo names.
