What's on Mayor Bloomberg's mind? Facebook and real estate! The Observer reports that the mayor said he "met with people from Facebook the other day. They’re opening an office here." Bloomberg pointed out, "This is the business capital of the world and Facebook is one of those advertiser-supported services. The last time I checked they had over two hundred million users. It’s a phenomenally successful service and I’m just thrilled that they want to have a New York office." However, the social networking site (coincidentally featured on the cover of New York this week) wouldn't confirm or deny the mayor's statement—and Facebook does have some office space in NYC (though perhaps it will be upgrading). By the way, Mayor Bloomberg doesn't have a Facebook profile, just a re-election campaign page.
