Has anyone heard of this? This company, YouData, allows you to create a profile of preferences (e.g. dining, travel). Through this profile, advertisers can reach out to target customers... Cool thing is that you get paid through PayPal, or choose to donate, after clicking or watching the suggested ad. Sure, it's a small amount, but maybe it adds up? Who knows. Anyway, I thought it was a unique idea. If anyone wants to check it out, here's the reference link I was given: http://www.youdata.com/join/fzr11017
IIRC, referral links where the OP benefits is a no no on this site (unless you are gaining nothing). I could be wrong though. I seem to recall someone getting flamed for it.
