I prefer uncensored.citadel.org. Yes, no https support, but you can login over SSH with ssh bbs@uncensored.citadel.org and use it as a modern BBS. It works great.

I'm not in love with the interface to be honest. It's great if you want to consume absolutely everything, but if you want to pick and choose in a topic thread there isn't a summary view as far as I can tell. It's kind of like reading specific #hashtags on Twitter.

warning for other users: i randomly clicked on the israel subforum and politics one and... yikes. chan-level bigotry

I love finding these retro-net communities. Another good one is the bboard at sdf.org.
