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.
Right, then your question should be “What made you join Lemmy?”.
Lemmy.world is just one of many lemmy instances.
I will correct it, I now see I botched the first title question.
