Usenet still exists and is actually getting better with time. There's not much spam and the only people there left are geeks that care about the topic. The eternal september is over and it's time to start again. You can get text only access for your usenet client (or use a web interface) at https://www.eternal-september.org/ . I post on alt.startrek and alt.cyberpunk every now and then and get decent conversations. I also posted back in the 90s.

Usenet need not rely on google groups mangling of deja news.
