I don’t know if it’s a new thing, or if I just noticed it, but several folks have posted items noting their oldest Usenet posting, as garnered from Google Groups.
I don’t remember ever getting involved with Usenet as such. Bitnet, on the other hand…
The oldest one with my name attached locatable via Google Groups is here from March 18, 1992–and it’s an odd post. From the right list, though, PACS-L; possibly not where I did my earliest Bitnet posts, but close enough.
Thing is, PACS-L started a long time before 1992. The list started some time in the late 1980s (Charles W. Bailey, Jr. knows for sure); the associated journal, The Public-Access Computer Systems Review, was founded in July 1989 and began publishing in 1990. I was associated with the journal (to some extent) throughout its life, and was reasonably active on PACS-L from early days. So there’s a bunch of missing Bitnet history at Google Groups; maybe it wasn’t echoed on Usenet until the 1990s.
(The oldest Google Groups post containing “Walt Crawford” is here, and is an announcement of an issue of PACS Review volume 2; given my feelings about Stevan Harnad these days, it’s odd to have a Psycoloquy post be the earliest. Such is “history.”)
