With those sorts of numbers I'm sure they could optimise and monetize the site better than that. I bet if they had a paid email list ($5-10/yr)where you got the debunks/explanations 24-48 hours ahead of anyone else you'd get quite a few conversiosns. Maybe even enough revenue to change the horrid site design and clunky search.
Great site though.
