So people have been saying, "Philosophers are getting on Facebook, you should too."

So I did.  Now what?  

UPDATE:  Well, I've now received lots of invitations to join other philosophers on Facebook as "friends," so that's at least part of the "what"!  Thanks for the invites.  I've also gotten invites from some people I don't know.  Perhaps one of my new Facebook friends will write on my "wall" explaining the protocols of this to me.
