Define "Fan". I enjoy his characters in the programs in which I have seen him (Star Trek: TNG, The Guild, and The Big Bang Theory), though I must admit that if he is anything like the characters he portays, I would not want to be his friend in real life. Furthermore, I don't and will never observe him on any social networking site, look up news about him, or see a movie/show simply because he is in it.
Trust me. I saw him play Rock Band at Emerald City ComiCon.
He is nothing like Wesley Crusher. In fact, he hates Wesley (or at least what the writers turned Wesley into).
