Facebook WTF?

[NajdorfDefense]

I'm not on there, but still:

'Social-networking Web site Facebook Inc. is quietly working on a new advertising system that would let marketers target users with ads based on the massive amounts of information people reveal on the site about themselves.

Eventually, it hopes to refine the system to allow it to predict what products and services users might be interested in even before they have specifically mentioned an area.

As the industry watches the Palo Alto, Calif., start-up to see if it can translate its popularity into bigger profits, Facebook has made the new ad plan its top priority, say people familiar with the matter. The plan is at an early stage and could change, but the aim is to unveil a basic version of the service late this fall.'
