Godin on Billboards

Seth Godin has an excellent post up about billboards and a thought on if they actually work. I myself have often wondered why there are so many billboards for things that aren't for sale immediately. Mercy Health Systems advertising to the same commuters everyday from Milton to Janesville isn't going to sell heart surgery. In my opinion if you can't put "next exit" on the sign, then you shouldn't be paying for it.

Update: A few posts later (as I read through my RSS feeds) Godin posts a picture of some billboard irony.
