Ehh, not a big fan of the whole democratic gm bit. Better to have 1 GM and 1 co-gm than everyone having a say in how things go down.
Cuts down on surprises and can just get boring and chaotic. I also feel that its better to have a GM that's a non-player, And/or one that won't be bias.
Some GMs that have had players in an RP tended to favor their character while giving other the short end of the stick.
