Sucks, right, because on the theadiverse, you're not actually able to do that so easily.Sounds like an unnecessary limitation of threadiverse software. Why limit a post to only one community? That doesn't make any sense.The person who made the post with multiple mentions clearly did it intentionally, and I would do the same because for every topic I am interested in there are 4-5 groups on different servers.Every mentioned person gets addressedIn most cases, this is what a user wants. Some platforms support silent mentions, though (Friendica, if I remember correctly).hashtag / community tag soupI think this should be viewed as a moderation problem, not a protocol problem. If you don't want to see mention soup, just limit the number of mentions per post on your instance.

Meh, I don't see this as a problem. People already crosspost into multiple relevant communities. If anything doing so with one post is a feature that's missing from Lemmy/Piefed. Or is it missing? I'll try posting into multiple communities after this comment.

It seems to me that your problem is more aesthetic in nature. Maybe ask your favourite UI to make a feature to hide mentions and hashtags that are alone on their line.

So what if Lemmy, Piefed, Mbin, and NodeBB made it so that only the first matching community gets the post?

Not sure about the others, but doesn't Lemmy do that already (only applies the first matching community)? I've been out of the loop for several months, so maybe it changed, but I thought it already did that?

I'm pretty sure Mbin already does that with sorting posts into communities based on their hashtags. Does it not do it with mentions too? I can't really test it since 99% of federated posts only mention one community, if any. So I'm struggling to find a post that mentions two communities, let alone two that are active enough on my instance to compare them.

But like, is it actually an issue? I always get the impression Lemmy users have more of a problem with the hashtags and mentions in general, not with the fact the post appears in multiple communities. Which would be easily solved by having their instance remove those from microblog posts.

We can already tell which posts come from threadiverse software and which don't (because we use audience, Mastodon doesn't.)

I honestly don't think that's a good way to decide between threadiverse and others in general. There's no guarantee non-threadiverse software won't make use of it in the future.

Can I get an example post or something? Im not seeing the issue?
