Google Automatic Matching Beta = Pay, Spray and Pray?

They say playing the lottery is a “special tax” for the “math challenged.” I think that’s true. In the search world Google’s new Automatic Matching setup is a special tax on the uninformed advertiser.

What I’m hearing about the new Google Automatic Matching beta is that they will look at unspent funds in your account, and “spend it for you” on terms its algorithms deem appropriate. I blew this off at first thinking it sounded like a rumor, but am now hearing more buzz about it.
