If you're in the mood for a little bit of nerd humor, check out Piled Higher and Deeper. It's a comic strip that chronicles the live of four graduate students (three techies and a humanities student) as they work their way through their respective programs -
Be warned if you're a graduate student (or even junior faculty)-- there are several years of strips, so it could be a real time waster. On occasion, it nails the doctoral student experience.
