@jalefkowit It's called a groups feature. GNU Social has it, it's fantastic and works across instances just fine. It's basically a relay to pass tagged group messages and responses to all members subscribed to the group.
If Mastodon adopted it, that would be the best thing ever.
@saper @jalefkowit No, those two things service completely different utilities. Hashtags are relative to your instance and contacts, bangtags are a signifier for group relays of posts.
@jalefkowit @saper Generally, bangtags only work if you're already part of a group.
@deadsuperhero @jalefkowit I fully agree that they are not the same and work differently; from what I read is that groups wouldn't be needed if hashtags federated nicely. I think it is a problem of all multicast protocols (how should a sender/relay know you are interested if you didn't subscribe first).
I used to think that, but I've come to disagree with your assessment.
Hashtags are more event-driven are topical, and require no subscription to a group, whereas a group exists specifically to provision the passing of messages to all participants, regardless of the subject of content.
@deadsuperhero @jalefkowit I somehow feel bangtags are just a hack due to difficulty in making hashtags to federate.
They are too heavyweight in my pretty (yet) uninformed opinion
