Hammer of Grammer has this WoW comic on the future of raids which is very funny. And so true.
I found this via Og's Ledger, a blog dedicated curiously enough to the art of WoW auction house flipping, buying low and selling high. Very interesting read. I'm not sure I'm doing Og a favor by linking to him, as I'm aware that some players consider AH flipping to be some sort of crime. I'd say it's just applied economics meeting bad AH design by Blizzard. But that would be the subject of a much longer post.
