On the oldest version of this site, I posted a list of the alt.* newsgroups available on Usenet. I put it up there in 1998, when I first set up the site, as a favor to folks who didn’t know how to search for newsgroups in their newsreader programs. Somewhere along the line, the file got truncated to 285K. As time went on, the number of newsgroups increased but the visibility of USENET (even as DejaNews and then Google Groups) declined.
On the rare occasions when I paid attention to my site statistics, I saw that the list had become a lightning rod for robots and perverts, and not much else. So I took it down. I was still a big fan of Usenet in the early 21st century, reading groups such as alt.drinks.scotch-whisky, alt.music.chapel-hill, and comp.risks almost every day.
Of course now, I haven’t read a Usenet newsgroup in years.
