Haha del.ico.us actually died for me when it moved to delicous.com. Used to be kind of popular with academics and librarians too at that time.

Not sure why I got downvoted. I was the first comment and just trying to clarify which site the submitter was talking about (since he said "delicious.com").

I upvoted you because I didn't know that delicious.com was del.icio.us.com until I read the comments.

The same product was served under both domains at different points in its life.
