Priuschat uses a company that posts ads that it solicits, on Priuschat. It is how Priuschat makes most of its income. The company Danny chose has "green" ads/sponsors. Since the Fusion is a hybrid it probably uses this company to hit "green" web sites.
What's really funny is that the Google Syndicate advertising - or whatever they're called - polls the page and picks ads relative to that page. So at one time, a thread about the "Dust to Dust" report claiming that Hummers were more eco friendly than Prii was being populated with Hummer ads.
