I know I link to it every week, but seriously, this is the best page in comics history.
Also, the forum has really been active lately. I get a few new people every day, and a few of them even post things. I'd like to see that community develop a bit more as the summer progresses. So, if you're interested, sign up.
Finally, Brightly Wound is back to updating for all you physics ubergeeks out there.
