The problem with titles is that they are reflected upon much like symbolism. If you give yourself a title you're giving everyone else a definition by which to place you, even if you don't agree with that definition. That's a sociological issue though, i'm not sure the words geek and nerd are really that controversial and frankly haven't heard them used excessively until I started attending college for Game Design. One of the questions on my application to the school was for me to define what "geek" meant and if I considered myself one. I found that a really peculiar question to ask on a college application.
