Yeah, I concur. I mean, instances have a "global stream" where all posts from all users are sent? What's the use for that? It would be like Facebook or Twitter

Yeah, I concur. I mean, instances have a "global stream" where all posts from all users are sent? What's the use for that? It would be like Facebook or Twitter having a "front page" showing all posts from all their users. I don't want to read what something posted merely because they're subscribed to the same physical server. There should be some classification of affinity by common interests.
