Remember you can cross post!

If you're looking at a post, it's the small icon with two squares. If you click it, you can send it over to another community on any instance. Not only does that community get the content (which is good for everyone), but there's also a "cross posted to blah" link on both ends that lists the other community. Also, if people are subscribed to both communities and using the web interface (rather than Jerboa), they only see one copy of the post even though it's on two communities.

Of course, don't spam, but to me it seems like a reasonable way to "get the word out" about overlapping communities.

Completely agree - I set up some communities on .world and have spoken to others who did the same.

I reached out to the owner of Dungeon World here to discuss what we should do, and we are going to figure that out - the community here is far more active so it may be a case of repointing or keep both etc who knows. All very nice conversation, nothing rude just people trying to figure things out together!

The kind of behaviour being seen where people are being asked to move here is what happened with Android and left a bad taste in a lot of people's mouths as it was a large existing community shut down by one person. It also can't be good for the community as a whole if people are rude, harassing, etc and that kind of behaviour will make people go elsewhere and rightly so. I don't understand why people are like that.

There are issues with having duplicate communities as well as benefits, but being a dick about it isn't a great look.

The TTRPG community on Reddit could be pretty hostile and rude, I was hoping here it could be different! My own experience has been okay - first impressions from some other people hasn't been great.

The fact that this post is necessary is surprising and unfortunate.

I fully support this. This is not a zero sum game, they are not "competition" or whatever you may think, and other instances/communities have all the same right to exist and thrive as we do.

I have a question about "the fediverse" and crossposting - I know that mastodon servers use "fediverse" as a term as well. Is there any compatibility between Lemmy and Mastodon content? (e.g. can I crosspost a Lemmy post into Mastodon or vice-versa?) - It would be really cool if I could quickly port my mastodon posts here for when the content is relevant.

The whole Fediverse must learn of our peaceful ways! By force!

Multiple communities across the fediverse for the same topic is a feature, and not a bug!

Yes! Part of why Usenet was so unsustainable was them only wanting one community for each topic. If communities are centralized things won't scale very well.

And, since it's federated, you can use your account to reply to posts across these communities while still having your main fave places you hang out at.
