I joined because Reddit has become a cesspool of bots and toxic behaviour. Lemmy is still completely open-sourced, while Reddit isn’t at all now. Also, when you first sign up on Reddit currently, you get completely ignored now and can’t post or comment on regular subs.
You asked about lemmy.world specifically. They are on lemmy but not on lemmy.world. People from different instances talking to each other is the whole point of lemmy (and the fediverse as a whole).
I meant just Lemmy, I fixed it. Which is another good option here. Editing the titles.
