Each sub forum seems to have died suddenly at some date, different for each one. What's going on here? It's like the scene in a book where they're going through the remains of some dead civilization and saying "food still on the table, doors open... Whatever happened here, it happened suddenly."

The eruption of Mount Stackoverflow has perfectly preserved these poor, Perl-scripting souls.

I guess with this revealed as being fake, the solution is: each "subforum" is really the copy of a different newsgroup, and each copy was covering a different time range.

Figures. What a disappointing mystery.
