50 Skills All Geeks Should Have

I saw this article earlier today called "50 Skills Every Real Geek Should Have". I went through this list and I'm lacking some of these, but for the most part I have them down. I'm actually typing on a computer that I build about a year ago, and would "tomato" my router if it wasn't the 2MB flash version. I just really enjoyed this list and some of the nerdy things it had in it that I deal with on a day to day basis. I would add on to this "how to use and interpret a packet sniffer", but I'm not clever enough to make a list like this so I'll let their list stick.
