Ask HN: What are your favorite newsgroups on Usenet?

I just bought usenapp (https://www.usenapp.com/) after using Unison for ages on mac. This is a useful backbone map of the usenet networks: https://upload.wikimedia.org/wikipedia/commons/7/7d/Usenet_P...

I have a hefty block account that's my primary server, and then a TB of block data from other backbones set to be only used when my primary server is missing data.

sci.crypt has fun stuff from time to time, if you like cryptography topics. comp.lang.c is also nice, if you filter off-topic posters.

They also recently started a usenet newsgroup for the Gemini protocol, but it's not widely known yet.

What clients are people using for Usenet these days?

I think Thunderbird is the only cross platform GUI app
