10d Things that, if they became public knowledge, could get me kicked out of the Geek club.
So why am I posting them on the intertubes?

10: I have never read The Hitchhiker's Guide to the Galaxy.
9: I don't much care for tabletop games, such as roleplaying games, TCGs, CCGs, or miniatures games, and have never played D&D.
8: I have never listened to a "podcast".
7: I have never learned or used the following: JavaScript, PHP, Python, CSS.
6: I don't have a dual-boot Linux box.
5: I actually rather like Windows Vista.
4: I can't solve a Rubik's Cube.
3: I have never played a Final Fantasy game.
2: Likewise with Zelda.
1: I love all the Star Wars movies, including the prequels. And I think the Ewoks are cool.

--Update 7/7--
Thought of another one.
0: I have never edited Wikipedia.
