Am I not allowed to start a conversation thread on a website where I specifically know there's many old developers who were around for that era? Of course I could use google or gpt - this is more informative.

I didn't say anything about what you're allowed to do.

"this is more informative"

As someone who was on usenet before it was even called that, I can authoritatively say that it isn't. I can tell you that many of the claims here are false ... e.g., someone claimed that the name "usenet" came from news organizations in 1993/1994, but in fact the name was voted on at a 1982 USENIX conference (and I was present and voted).
