Any recommendations for a free trial?

I was very active on usenet from 1980 through the 90s. Even built my own nntp client. But I drifted away.

Now I'm considering getting back into it. I would like to see how things have changed. I appreciate the relative lack of enshittification and lower incidence of astroturfing. Hopefully things haven't gotten crappy in the way that, say, Reddit has.

Any recs?
