>> "So why did we switch to delicious.com? We’ve seen a zillion different confusions and misspellings of “del.icio.us” over the years (for example, “de.licio.us”, “del.icio.us.com”, and “del.licio.us”), so moving to delicious.com will make it easier for people to find the site and share it with their friends. Of course the old del.icio.us domain and all its URLs will continue to work. Also note that the domain change requires a new login cookie, which is why everyone has to log in again."
