Someone sent me this article and I thought it was worth throwing out for discussion -
Some interesting points, but I *really* doubt this is what Google has in mind.
Even though fraud occurs, I think most *smart* advertisers who use Adwords know the return they're getting on their ad dollars and take the appropriate action.
If I can keep buying .05 clicks and generate a 40% to 50% return, I can stomach a little fraud... I also have a hard time believing that Google would shut off the revenue stream that made half the company millionaires...
