For me, it is really about the history and the statistics. I love reading about the minutia of every little thing that a player does and how it counts for something, AND there are people that keep track of it. I think that is why people are so pissed about the steroid players - they fucked up the statistics, and therefore the history of the game. I think that it has less to do with keeping the purity of the game in tact or morality.
I could go on, but seeing as how I (and now maybe Jr0n) are the only ones really into it, I'll digress.
Jr0n, I'm available to talk baseball anytime!
