Facebook grows up with many visitors over age 35

The number of Facebook visitors 35 and older more than doubled in June to 11.5 million, or about 41 percent of the site’s visitors.
 It’s a new demographic that will bring changes.
 Right now, Facebook allows people some control over what information they reveal to various levels of “friends.” Level one is probably ex-dorm buddies and girlfriends, level two might include sales contacts and fantasy-league teammates, and level three is likely to be anyone who signs off on performance reviews.

 Visitors find they can build social capital with little effort, maybe just by sending a birthday greeting.
 One employer uses Facebook to reach people he can’t otherwise find.
