I initially chose it because (I think) it didn’t require me to wait to get approved. Or I just forgot about that again. Another reason was because of the post lemmy.ml asking people to join elsewhere because there were so many new people it got difficult for their server to handle and lemmy.world was the next I saw.

I did make multiple accounts (on different instances) though to have a sort of backup just in case something happens, as unlikely as that may seem.
