Reality Enquirer

I notice more and more sites are beginning the annual request for donations. I am starting to wonder how much it really costs to run one of these sites, and how much these people are really making off donations. From what I understand the popular sites are getting tens of thousands of people showing up each day - if they could get money from even 1% of those people they would have thousands of dollars. So are donations really good, and do they just cover costs or is it a profit bonanza for these sites?
