Not much on my Links page right now, since it was pruned. But a few interesting sites remain.
Elven Empire - One of my players. This page has several sections, including a humor section, but is mostly dedicated to his highly detailed campaign world for Dungeon and Dragons.
201Mass - A Slashdot-style gaming forum. Focused on the Boston area, but has other articles of interest.
FreeRoleplay - A site devoted to free RPGs.
The Forge - Game designers and commentators all gathered on a big message board.
