The best thing you can do for the fediverse is just be kind
The fediverse is small, and thats both a blessing and a curse - one of its several blessings is that in a smaller space we all individually have a bigger impact on what the culture of this space is like.
On this comm (and on lemmy broadly) there's a lot of discussion about how to grow the fediverse, what to improve, but an easy thing you can do for the fediverse is right in front of us-
Be kind
Ask people what they think, and why
Approach folks you disagree with with curiosity rather than hostility (EDIT: no, this is not specifically referring to Nazis. I get it, they're the first thing that comes to mind. I'm not telling you to approve of Nazis I'm just saying be kind to your fellow lemmites)
Engage sincerely
Ask yourself if there's something nice you can say
Make this small space worth being in
A platform lives or dies by what's available on said platform and often we have this conversation in the context of "content" or posts - and we may never have as much content as reddit does. But content and posts aren't the only thing this kind of platform offers- it also offers people. It offers community, and human interaction.
Culture and community is lemmy and the fediverse's biggest differentiator, and we all have a role to play in shaping the culture of this space.
The biggest thing you can do to help the fediverse is make it a place worth being.
ngl this is such a toxic community. The Nazi thing is definitely part of the problem -- we live in an age of "soft fascism" so of course we have our fists up and we see nazis everywhere. Honestly I think most of the nazis are on twitter or truth social though, they don't come to lemmy so much. Hmm, don't assume that someone espousing an (1) conservative-looking belief is a nazi maybe?
The amount of times I've been blocked on the fediverse because I've mentioned that I find the mechanics behind AI interesting, or the math behind crypto, its actually insane. Or anything positive about spacex or the benefits of a free market.
