The problem I have with those del.icio.us type urls is that I have a really hard time remembering where the dots go.

Way back when del.icio.us was just getting popular, someone told me about it. When I got home, I tried "delicio.us", "delicious.com", "de.licio.us", etc. Had to resort to googling to find the place.

Also, you have "con.nect.us", but who has "connect.us"? I think they'll be getting a lot of your traffic...
