Unfortunately for you the rest of the commercial world disagrees, and I can assure you a chain like Hyatt doesn't view BoardingArea as a "commercial venture". Just because Flyertalk has a weird fascination with the site and appears to devote an entire forum to bashing the site and its writers, doesn't mean a hotel chain sees it the same way. All blogs have banners and affiliate links. Just visit a large site like Engadget, Huffington Post or TechCrunch. Something has to pay the bills.
