I'm a proud geek, a professional geek – Geek Upgraded, Geek 2.0 if you would. I make money with being a nerd, a fan, it's my life. A lot of us are, or are partially, but sometimes we miss something when talking to our fellow geeks and fans.
We miss that people are often made to feel BAD about their fannishness, what they geek over, etc. You, the reader, may be a person who'd like to make a living at what you love, but you're used to feeling that your hobbies are a bit silly, or immature, or irrelevant. Despite shows with geek heroes, it's a bit hard to stand up and say, for instance, that you really want to be a novelist of fantasy fiction (even with the success of say, JK Rowling or Terry Pratchett).
These self-esteem issues are difficult on the potential professional geek (if not the current professional geek). Most anyone knows that self-esteem issues can shoow down the greatest of minds and the deepest of imaginations.
