i think a wikipedia article would be wonderful -- i hope someone else does all the work.
seriously, we should consider what, precisely, someone who is not involved in BuzzerBeater would be interested in if they were to reference the article. i'm not sure they would be as fascinated as we participants are by a history of the results -- champions, records, what have you.
for myself, i find the mathematical / statistical structure of the game to be of primary interest. i am fascinated by the creation of a "reality", with randomness included, that is completely the result of math. unlike many who participate in this game, my knowledge of statistics, programming, and who knows what else (linear algebra? are algorithms a form of calculus?), i don't nothing 'bout no mathematics. but i find this exercise in modeling the basketball universe to be absolutely fascinating -- and it helps me to understand other models (say, for predicting the weather, the economy, or estimating the amount of oil that may exist below the seas above the arctic circle). i would suggest that at least some of the Wiki article deal with this aspect of the BB -- i think at least part of the audience would be interested in this.
