I think if we want Hive to be more like a replacement to current social media, we're going to need some basic privacy functions like blocking, and posting between just your friends and posting publicly. You mention that common social media behaviors get flagged here and I've seen that too - if you can post just to your friend group with your hanging out, day to day stuff, then people can do that freely and only their friends see it so it doesn't get flagged. Those that want to post public blogs can set them to public. A big thing that people say when I tell them about Hive is, "I wouldn't know what to write about," because they don't want to write blog posts. And even as far as blogging goes, it doesn't have the functionality of most blog sites - you can't categorize your own blog so people can read about just the topics they're interested in and you can't even find your own old posts to reference back to. If we could make our own categories, that would be great.
These are possibly different front end ideas; which (if any) front end wants to act like social media, which (if any) wants to act like a blog site.
But yeah, I feel like we have some very well-developed niches and some wholly underdeveloped ones. I wish I was a dev so I knew how to make the features I want. :)
