I knew that you didn't mean your list as a quiz, but I thought that it would be fun to treat it as if it was. If you had asked me when I was 20, I would have scored much higher on the standard geek scale, since my fascination with all things computer has worn off somewhat over the years. On the other subjects you mentioned, just for fun, here goes:

1. Gaming: I prefer simple games. I prefer Solitare and Asteroids to the harder computer games, and I played the geek classic Dungeons and Dragons only once. It was much too complex for me. I like simple games because in my work and in my other pursuits I do such complex stuff that I need a simple game as a break.
2. Star Trek: I watched Trek a great deal as a kid, because it was better than most of the crap that was on TV. Give me anything better, and I will watch that instead. I do like Star Trek: New Voyages because it shows that high-quality TV can be made outside the studio system on a relatively limited budget.
3. Sci-fi: I like sci-fi, but not for the same reasons that most of the geeks that I know like it. The spaceships and tech don't fascinate me. I like sci-fi because if often asks questions about philosophy and ethics that your standard mystery or romance doesn't ask. I will read stories in any genre that asks these questions and shows how people confront these issues.
4. Diet: What is a geek diet? Do geeks prefer Asian food, like I do?
