I see and totally agree with you. I am always thinking what are the main keys for the Hive community to grow. Probably when there will be more people on the platform, there will be more taxonomies. Or so-called communities. It is on communities to filter good posts and keep curators just to confirm it not find new "stars".
Maybe the main problems lay in my view of Hive. I embraced it as a good quality source of independent news. I have even ideas about apps for this but sadly no knowledge nor time, to be honest.
