The targeting offered covers the following sofar:
the Flyers let you target by country, city, gender, age range, political views, relationship status, education level, workplace affiliation, or any keyword in a personâ€™s stated interests. Itâ€™s that last option that could be really powerful. For instance, simply putting in different keywords into the Facebook Flyers ad-targeting page reveals that of the 19,951,900 Facebook members in the U.S., 101,000 are into rock climbing, 411,000 are into cooking, and 706,160 people are into traveling.
Regarding Facebook: there are already many rumours spreading. And depending on who is seen with whom in photos (which are so blurry you can’t see anything), the valuations for Facebook are going up and up. Currently at $15 billion.
According to the this article, MySpace is going into the same direction offering targeted advertising.
