Colin has very patiently reasoned with you about what may have happened (for the record, I didn't flag that story, and I would never have visited it at all but for the question I'm seeing in this thread). There is no reason to be argumentative with Colin; he is just trying to help.
I agree that lists of three-letter domains, or four-letter domains, with this or that top-level domain suffix make for dreadfully boring submissions. I think some people massively overestimate the usefulness of a cute domain name. Hacker News gets plenty of interest even with a domain name like
news.ycombinator.com
and other sites too have better eyeball-attraction value than their names might suggest.
