A single feed with communities, friends, trending and hot mixed in together, maybe throw snaps and waves in the middle and play with an infinite scrolling-like algorithm that adapts to your engagement on posts and comments.
Huge task, revolutionary payoff. The timeline-like feed Hive has is outdated and makes it hard to explore new stuff and it can't recommend what interests us.
I value the timeline-like feed to keep up with friends, but the community, trending and hot are built in the blockchain, they are stuck in time bound to get old, sadly they often have too much irrelevant stuff, so I go back to to reddit, Instagram or anywhere else where each refresh or each scroll give me stuff I may be interested in (along with stuff I may not just for discoverability)
edit: may be the discovery feed? mine is not engaging but may be due to my activity? maybe it improves as I use? anyways it is the same after I refresh, an infinte feed needs fresh stuff per refresh
