Google local referral

http://www.google.com/services/local-business-referrals/about.html
Just read about google's local business referral scheme. Its a brilliant marketing idea. The idea is to get the public to contribute information to their database and the public get paid for it. The beauty of it is, Google, now has access to information that wasn't previously on the internet... essentially they are creating content on the web. Of course, Google will try to sell AdWords to all the shops and increase their customer base and, thereby add to their already overflowing bank account. Obviously somebody has done the math and figured out that a one time payment of 10$ per business can still make the whole thing profitable. This whole exercise goes to show the power of money and "it takes money to make more money".
