Hmmm... Well in that case for more evidence I am going to have to fall back on the assertion that I remember hearing a reference to it being set up in the 90s by a physics professor as a joke, in a documentary about memes on BBC Radio 4:

Although you can't stream that programme and I appreciate that my half-recollections are hardly convincing.

What does seem likely is that the site was in fact set up in the 90s by a physics professor as a joke, and since then it has been used to make money, precisely because it was popular and unusual at the time. Maybe he sold it to someone back in the good old 90s bubble, when men were men and a domain name was a business model.

(Fun Fact: That documentary was presented by the woman who wrote the article about LSD that was on here recently.)
