Most of this thread is devoted to correcting his understanding of Usenet history rather than providing useful info. What he wants is to find subject-focused discussion forums. The answer is to stop thinking in terms of Usenet and look for forums on special interest web sites. You can find anything from boardgaming (https://boardgamegeek.com/ https://boardgamegeek.com/) to computational fluid dynamics (https://www.cfd-online.com/ https://www.cfd-online.com/). I find the best forum experience is when you have strong moderation by subject-area specialists whose only concern is to keep things on-topic.
