Arisuchan and lainchan are good, too. Smaller than 8ch, but that's okay. It's good that there's lots of these little places around. Everyone knows more and more niche communities are going to be shut down by big tech, chans blocked by repressive governments or de-platformed by their registrars, etc. The internet counter-culture community - which spans a lot of political and social alignments - has a strength in being flexible and ready to rebuild elsewhere and not hung up about losing a handle and all that time spent "building my personal brand" like normalfags on twitter and shit. Embrace the chaos.
