Much of the blogosphere has been lit up with Facebook's new ad platform.

It's pretty impressive. It's an automated, scaleable Raving Fan Strategy that can lead directly to sales.

The other night, I made a car reservation on Hotwire and as I checked out, got a message that said basically, "would it be ok if we mentioned that Jeremy got a great deal on Hotwire on your Facebook news feed?"

Whoa!

And just like that, everyone knows what I did.

I should have taken a screen shot. Very impressive.
