I feel like Fediverse users are nicer to each other and more generous with upvotes than reddit.
i’m doing it because I want to make the fediverse more friendly place, in hopes of making it more welcoming for new users, and the nicer place in general. But I wonder how much is just less bots.
Every platform is nice at the start, for mainly the reason you say: people who join early have an interest in the platform, so we actually try to keep it nice.
Then every successful new platform gets its own eternal september. A large influx of people who don't care about the platform at all, they just want to use it to talk to people. And of these, yes many are still nice people, but also many aren't.
You see this in all kinds of communities, not just online. If you're in a new or niche hobby, everybody there will have an interest in improving the hobby and the small community, so it will probably be very nice. When it gets mainstream (I'm looking at MTG here, but other people probably know other examples) then it starts to attract people who do nothing but complain.
This is it. I'm not sure how young the crowd is here but those of us that have been around for the start of a lot of platforms have seen this happen plenty. It's always nice to start with. Then that fades.
