I've been having fun seeing the menus I created for my site pop up elsewhere. I usually find out about these when I see some page referrals in my web log from sites I don't recognize, so I go to investigate to see who's talking about me. ;)
I've found another site here in the US, dewjoy.net, another site in Australia, A Yobbo's View, and another site from Russia, The Private Daily Times. Pretty cool!
