Interest based advertising means that the fact that someone visited a site aimed at a high value niche can be used to show them the high cost ads on other sites.

Thats a good point, havn't read the whole volume of threads on this but I think it may be the first time it was brought up. It seems odd though, few have yet to see that in effect, just plummeting epc and ctr. There seems to be alouder uproar of 'earnings are down' than usual.

interest-based should replace public service ads

That seems like a great idea.
