A story, part 1 of 3, from Online Media Daily entitled "Search Engines Prepare For Behavioral Targeting: Part One Of A Three-Part Series".

Nothing too deep, wet-dream stuff for those Ad folks not bemoaning the loss of KISS principles. Some lovely quotes from Gator (damn, Claria) including:

For instance, adware company Claria hopes to sell engines and portals on the superiority of its own client side solution, an always-on toolbar or desktop tool that assembles richer profiles from the full range of user behaviors rather than activity occurring within a site or portal. "If you only rely on site-specific information, you don't see over 95 percent of people's interests," says Chief Marketing Officer Scott Eagle.

Lovely.
