"soon to become http://delicious.com/your_username"
Del-dot-issio-dot-us.
Or, my favorite, a friend who pronounced periods by coughing. We kept offering him water.
It's a bit ridiculous that icio.us was never set to redirect, though. What a waste of a domain name. Unless there's a good SEO reason to do that?
I never changed it because the most active part of the userbase liked it.
Anyway, I think you misread the comment. How come just "icio.us" (no del subdomain) doesn't redirect to the full del.icio.us?
Way back there was a second copy of delicious set up at susp.icio.us for testing, but I had to take it down as people were using it.
And I agree with above: I'm always amazed at the sorts of people that read HN.
