I love wikipedia. I would pay good money for that. People used to, back when they bought encyclopedias. At least $100/yr.
If I had to pay for access to my email (yahoo) I would just switch to another service. I would be willing to pay a small amount for gmail, which I also have, since I really like google docs. Maybe $10-20.
I'd pay about $40/year for IMDb. It's useful and I waste a ton of time on it.
I'd have to pay for jake and amir and xkcd. Probably whatever a newspaper subscription is, that's what I'd pay.
I'd pay $40 for CC and my other forum each.
