Yes, I second that

I agree totally with Lexington;

Now that it's official—Facebook has half a billion users—I feel at last that I have a reply for my wife. She (60) has been mocking me for having a Facebook account at my age (59). For the past year my mendacious excuse has been that I joined to keep a weather eye on what my children (30 and 28) are up to. But now I can tell her that half a billion members can't all be wrong. Facebook is not just a useful tool but oddly comforting.
