A third change is a reaction to some criticism about long pages and not enough structure. But what really propelled me to action was a conversion of the statistics generated by XS4all to something that was easier to understand. The statistics as generated by XS4all are a bit difficult to follow, as only the filename and not the title of a page is mentioned. In december 1998, I organized it in a way to be able to understand what was happening on the site. Here is the hit list of November 1998.
Chemistry is by far the most popular, followed by mathematics, pranks and physics.
This is a far different order than the number of jokes, which is mathematics, physics and then chemistry with pranks far behind. In the mnemonics section the order is a bit different. Chemistry again on top, followed by biology. Physics and mathematics lie behind that. So mathematicians like to make jokes and chemists like to read them.
