Misnomer -- this isn't an enterprise version of Facebook, a la Yammer, but a portal for how businesses can use Facebook. The title of the page is "Learn how to grow your business with Facebook's powerful marketing tools"...
(Yammer employees reading this can thank me later)
I don't get it... what's new? Is this even new?
I'm sure I saw that a long time ago. It's just a landing page to explain how businesses can use Facebook (i.e. with ads or pages etc), right?
