the interesting part is that he says you basically bid on the placement yourself. Lots of publishers are paid via CPC, so only when clicks are made. I'm guessing this has to be CPM bid then, in which case to be effective you're going to burn through you $2 per month awfully fast.

Another thing - if you're actually taking part in the bidding process this is a trojan horse to jack up the bid prices (they work in an auction format roughly) for everyone else.

Well played, evil Google.
