Are most users here just for the laughs? I know redditors were anti- 4chan users typically
I used to post on 4chan and greentexts are kind of nostalgic to me. Some relevant context here is that the site becoming dominated by cultish far right politics was something that progressed over time, and there are probably a lot of people with an interest in imageboard culture who do not especially identify with the people currently posting on /pol/, for whatever that’s worth; those guys overrunning the site was a big factor in quitting for me.
What part of imageboard culture did you enjoy and in what ways to you find it different than forums like lemmy or reddit?
Some big ones were the greater anti authority sentiment, contrarianism, acceptability of expressing negative emotions. Reddit was often (though not always) better for polite formal-ish discussions, 4chan was better for processing your feelings about stuff via trash talking, dark humor and generally dropping your filters.
