  I've run into at least one newspaper website (I forget which,
it's occasionally used for links on Slashdot) which ends up trying to
redirect me to a Facebook site even though the URL does not mention
Facebook at all.  There is other integration as well.  See the first
post in
http://www.dslreports.com/forum/r26618459-Increasing-integration-of-facebook-into-many-web-sites
I believe this may have been straightened out since then, but 13 months
ago that post was correct.  And then there's the "LIKE" button which
shows up all over the web.

  The mere fact that you haven't manually typed in...
http://www.facebook.com/blah_blah_blah does not mean you're not
connecting to it.
