Eh, not really. If there is one thing Apple does really well, is that they don't enter markets they can't win. Social networking is one of those markets they can't win. I suppose you could say Ping is a social network, but honestly it is more of an experimental extension to iTunes, kind of like how Apple TV is an experimental addon product to iTunes.
If Apple is smart about it, they'll use Facebook to boost their other products (such as iTunes).
