Probably one of the reasons Google linked to them, is that they have so many Google ads on their pages (3 of them - quite disturbing to me).
And Google takes about 32% of the price paid by the advertiser.
Just a back-of-the-envelope calculation: let's assume 217000 page views, with a 1% CTR, and a 1$ CPC. The result (of that 1 day) : ~2000$.
