I have made true friendships online, some of which I've cherished for years. I call those people friends which they are and casual aquaintances via LJ and Facebook, blog buddies, scabble buddies ect. I would not defriend someone over disagreeing over an issue, for how dull life would be if we were all alike!

I guess we need a different word, but I don't know what. ff.net now sends messages saying "X is now following you" which sounds downright creepy!
