This may well be an accurate description of the current status of the nostrverse. But, I don't think it's the big Npubs' fault. I rather think this is mostly the inevitable dynamic that occurs in a system that's designed in this way (no feed algorithms at all). And I think it's kind of a bootstrap dynamic that mostly characterises the beginning of the network. After this initial phase I'd assume that other dynamics will evolve. New social circles/ sub communities will form around high impact accounts that have nothing to do with the initial big Npubs. So I think we need patience and we'll get slow evolution, because every npub is slowly bootstrapping their way according to their interests.
The slow evolution of each npub's follow list is where I'd like more tools from the client devs. I'd like features that help me with systematic management of my follow list(s). Example: Give me a single button on each note (accessible without _any_ additional tap/click, so that it's minimal effort) to mark the note as "interesting/relevant to me". Then show me statistics from these marks so that I can directly see for all my followed npubs: - number of notes seen in the last x days - % of these notes marked as relevant - ...
Another Example for a feature: Somehow help with categorising followed npubs. Categories could be: A, new info npubs (news bot or heavy poster, never replied to any of my replies, not following me back) B, high volume poster (not news bot like A, but frequent posts in discussions) C, low volume poster (but is following me back, replied to a few of my notes) D, ... And for each category I'd like a separately scrollable feed.
