While we try out reddit alternatives, why not try the open source reddit clone, lemmy. I honestly don’t know a whole lot about the whole fediverse, only heard about mastadon vs twitter recently but I never used twitter and don’t see a reason to start with mastadon. But the churning community is small enough and separate enough from main reddit, why not give it a try.
Initial signup is still a weird barrier for these federated sites. I kinda just picked one at random that seemed general.
I’m checking out Mlem, an iOS version. Not near as good as Apollo but it’s still in beta.
