I haven't read it. But I think computer geekery varies from person to person.
True geekery is when your professional life includes either some form of engineering or computer science and your hobby life consists of knowing many different types of programming scripts fluently and you know a lot about computer-related history, as well as being able to keep up with current technology and the market.
I consider myself only partially a geek and only because I really know just a little bit more than any average joe on the street. But being able to build and overclock your own PC doesn't make you a full blown geek as the learning curve for that is not that steep at all. The only thing I've ever done close to programming was ActionScript.
I took a test a while back online and it gave me a score of 48%. Some stuff in there just completely went over my head.
