What made you pick the Lemmy server you are on?

I picked lemmy.world because it was recommended and had a large userbase. I know Beehaw defederated from lemmy.world and sh.itjustwor.ks, so if you want to interact with that community, that could be a consideration against, but since the user population across all of Lemmy is currently increasing dramatically, I think everything's a bit of a moving target regardless.
