h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

This is interesting... I was polishing off my new entry on A Hypothetical Reality (go check it out! Nudge! Nudge! A2841158) and trying to find a link to a definition of anthropocentricity.
So I searched H2G2 for the keyword 'bigot', and the second entry, with score 14%, is the one at A1949097. BUT the subject is the same as the subject heading of my own userspace ("The earth is taken; this is not your home."). My interest is piqued, so I click on it to see who else thought this little quote makes a good subject heading.
I end up at my own page.

Well that explains the subject, but where the heck did the Entry number A1949097 come from? It's not mine, and even if it was one of my entries the link would have taken me there, not to my user space at U520822.

Is it a link to an entry which has been removed, yet somehow remains available to the hootoo search engine? Surely it's not a - Gasp! - bug in H2G2's otherwise perfect veneer?

Any ideas, anyone?

Incedentally, I'm feeling much better for having written the entry. And I forgot to mention in my last journal (a couple of hours ago) that I'm getting on better with my parents than I ever had before, so that's good. I think my father's recent unemployment troubles have made them more sympathetic to my life as a broke student. And they're getting more comfortable in their lives. I am pleased again.
