I can sympathize with those people in this thread who have not heard much unreleased stuff, I was one of those people until August of 2002 when I actually went out and did something about it (yes, you CAN make a difference). Traders are not always egomaniacs who want X number of discs for Y number of discs (those who do are assholes and need to be terminated with extreme prejudice, because they too had to start from nothing), a lot of them are very good people and will most likely hook a brother up if they don't have anything.
But patronizing those people who do have this stuff is most likely not going to make them want to give you anything. Traders want no part of bitter people.
I will ALWAYS hook someone up if they want something.
Good point about going out and getting it. I get sick of people who act like they are helpless finding bootlegs. You're on the internet! All bootleg traders have to start with nothing. I've managed to get great stuff with almost nothing to trade or by having to do 2:1 trades. Anyone can do it.
And usually the asshole traders don't even respond to your request anyway. Not a big deal.
