I read EN World, Circvs Maximvs, the official Wizards of the Coast forums, and RPG.Net. I probably spend more time on RPG.Net than anywhere else because the conversation about roleplaying is more mixed - I love me some D&D, so EN World is great, but there isn't a lot of talk about World of Darkness or GURPS or other games I enjoy around here.
I do visit the Paizo forums, but their format irritates me and, living in Australia, there's no (legal) way I can keep up with the conversation about the current magazines. I generally visit there for a specific reason, like reading the staff members' campaign journals or finding out when we can expect the Eberron conversion notes for Savage Tide.
