Obviously we're not going to link to places like YouTube or Wikipedia, but it would be useful to have some websites on the list which serve as debate/discussion resources or even just for the sheer joy of learning.
I'll start the ball rolling:
TalkOrigins - The premier resource for evolution facts and argument.
Debate Unlimited - by Martin Willett. Now, I know what some of you will say: Martin can be arrogant, abrasive and sometimes downright weird. I acknowledge that, but I also think that in places he has some extremely interesting ideas and takes on various issues.
Political Resources on the Net - Listings of political sites available on the Internet sorted by country.
