Why Do “Goths” Throw Terrible Conventions?

I just posted my experience with supposedly Gothic conventions elsewhere, but I thought I should perhaps start an actual entry thang about it.

GothCon in New Orleans did not impress me, but I had a great suite at a non-sucky hotel and had a lot of fun in Louisiana with my pals.

Convergence in Las Vegas, on the other hand, was the single worst convention I think I have ever been to under any circumstance anywhere, but I had a pretty good suite at a non-sucky hotel and had a lot of fun in Nevada with my pals.

Why do people who try to throw these things (a) get the worst hotels possible, (b) totally fail to put on decent programming, (c) inspire an atmosphere of unfriendliness, and (d) suck.
