Good point re: the baby. It's kinda like, I'll put up with your baby-watching shenanigans if it's free, because by definition, something that's free is not professional, so whatever.
I see your points and I agree with a lot of them. I listened to "The Bridge" episode, where they explain the process and their motivations... I think it's more along the lines of this: I don't think they want regular sponsors that they will be beholden to (I could be wrong about that) w/r/t content. And it sounds like they're just too busy to keep doing it if it doesn't pay money, because Jimmy's got a kid, Belknap's got a real job and the AST Empire to run, etc. It makes sense. I can relate in that I've come to similar conclusions about being in bands in the past. Like, I like being in this band, but it takes X amount of time out of my week, time I could be spending with loved ones, time I could be making money to pay all my bills, and time I could be working on art, and does the amount of work I put in "pay off" with or without money. I don't think it's greed, but they're in a different situation than Tom. Tom is part of a community, he started doing it a long time ago and he wasn't in it to forward himself professionally. Pardo is a career entertainer and his motivations are entirely different than Tom's. Correct me if I'm wrong, but WFMU is a much bigger entity than AST, there's probably a lot more legwork Matt and Jimmy have to do just to send the thing out into the world, Matt's producing everything himself, etc. Tom is literally not allowed to promote his CD's on-air, nor is he allowed to talk about his work. If he was, I'd suspect he'd promote Stereolaffs more. From the beginning, Stereolaffs has been Tom's solution to the same problem NNF is trying to solve.
But yeah, in Gervais's case that's just fucking greedy. Unless they're giving all the money to the dumb guy they make fun of the whole time.
