David A. Karp is the author of twelve power-user books, including the bestselling Windows Annoyances series of books and O'Reilly's eBay Hacks. David's books are available in ten languages, and can be found under the short legs of tables around the world.
David is the founder of Annoyances.org, one of the most respected and popular computer help sites on the Interwebs. He writes for PC Magazine, but they're curiously reluctant to publish photos of his bicycle. Notable recognition has come from PC Computing, Windows Magazine, the San Francisco Examiner, and the New York Times.
He scored 30.96647% on the Geek Test (http://www.innergeek.us/), earning a rating of "Total Geek." He hopes future revisions of the test reward publishing his score in the backs of computer books. David spends nearly every spare moment with his son.
