Yes, I was thinking about it in broader terms of the total bandwidth consumed on the web by these things. Say, for sake of argument, it's 10% of the total traffic. Now what does that traffic cost, and how much more money could the companies who have inefficient sites make if they were optimised properly and therefore running faster. That figure is probably a lot of money. My thought was there might be some way of tackling that large problem as a whole in some nice automated way and take a cut of the money somehow. A green business idea. Probably silly.
