"They" are a group of graduates over a 10 or 12 year span who all happen to play in a band together, and recently got an indie deal; first two albums now available for purchase on iTunes. Songs for the third album are currently in production, with some of the tracks cut at Sun Records. (If you are a music nerd of a certain age, this is Godhead - but if you're that age, you're not likely hanging out at wikipedia. This is part of the problem of a self-selecting "Board of Authority.") None of them are my family - I'm an old acquantance living 1,000 miles away who happens to be a fan.
Now, contrast them with the sleezeball wanna-be "sports agent" who lists himself as a "prominent graduate" on the same page, even though he has no clients and is totally unheard of in recruiting circles (at least the ones I participate in - does that make me an expert? No, of course not. He can stay up there if he wants. Or more accurately, if "they" want.) He's practically advertising to current student ball-players. But guys who make music I can purchase on iTunes? "Oh, they're not good enough."
Please note: I am now engaged in the same "debating picayune subjects with anonymous people" situation that I *didn't* want to be in, in the first place! It's ridiculous! I'm quitting!
Defend the wikipedia all you want, it's still a human endeavor... and human endeavors will always be swayed by cliques, groupthink, self-selection, etc, whether those endeavors are trivial "notable graduates from our HS" lists, or management of a collectivist nation. All the self-imposed "rules" in the world can't get around this immutable fact; the rules themselves carry the taint of human endeavor.
Perhaps we can agree on this at least: One day, the Robot Overlords will worry about this stuff for us! What was it Perry Ferrell said? "We'll make great pets?"
