What I dislike is double standards.
If you know how to overclock a CPU, install windows, what FSB stands for, and how to setup a network on here you're not a geek.
If you do RC cars, you're not a geek.
But you play an MMO you're a geek O.o
On the other hand, to others, knowing about PC's you're a geek, but they'll happily prattle on for 4 hours about the difference in fishing lines....
