4chan as a whole is dead, mods basically let shit and spam roll 24/7, gook needs to go and 90% of moderators fired.
8chan is conceptually different, board fragmentation destroys board culture.
7chan is a whole imageboard dedicated to ironic posting.
420chan is useless unless you want to talk about /x/ related stuff.
lainchan is discord trannies playground.
wizchan is incel larping playground.
At least this site has /a/ and /v/ which not much boards have, /r9k/ is not needed. 2chan and 4chan were built to have fun, not to talk about politics or depression.
