The Apple App Store is a great example of human curated discovery.
I'd love to crowd source a basic iteration of this, where there is a "pic of the day" with a short summary of the account/context
Another section could be dedicated to "under the radar" accounts
The community could vote on monthly themes, like say nature, and have a section dedicated to that
I want discovery to be a lot better, but not forget the humanity and emotion that a endless algorithmic feed would

A bit of a side note —
It is a poorly kept secret that you can get "featured" in the Apple App Store, Google Play Store, and ProductHunt if you pay them (a lot of) money.
(5-figure and 6-figure amounts, depends on where you want to get featured.)
You (often) just have to know the right employee or former employee to talk to to make it happen — as it (understandablely) isn't publicly advertised.
