Supposedly, nerds are now cool. People compete to show their nerd cred. They are joining Facebook, taking nerd tests on the Web, and discussing the definitions of geek and nerd on their blogs. They watch TV shows like "Battlestar Galactica," "Heroes" and "The Big Bang Theory." They read adult comics and mammoth science fiction novels. Even Barack Obama is said to be a nerd. It was not always this way, a topic that Benjamin Nugent explores in "American Nerd: The Story of My People," published earlier this year. I ordered the book after listening to Nugent give an interview on The Sound of Young America podcast about what he called his childhood experiences as a self-loathing nerd. It was poignant (and familiar) to hear him describe dumping his nerdy Dungeons & Dragons friends in high school so he could pass for normal. Unfortunately, the book did not quite live up to that interview, either intellectually or emotionally.
