If it's reddit for ads, then I'd think it's based on what you vote on. The process seems to work well enough that you shouldn't get too many ads for Ron Paul's site.
I got a chuckle out of that one.

an online survey and user account would make sense for this. I'm not sure how many people would use it.
i wrote this in another thread, but i would gladly spend a few minutes telling an ad-server what i'm interested in so that the ads are relevant.
