Thanks to the Greedy Goblin, I've found the twinks' website. There's lots of advice for the twinks themselves and as GG says, this is the place to find out what gear the twinks want if you are a seller.

For those new to the game, twinks are players (normally pretty low level) who pursue high level gear as their main focus of the game instead of raiding or running instances. They often compete in the Battlegrounds.
