Might be a controversial opinion on here, but I still think it would be cool for clients to experiment with an algorithmic feeds, even an additional feed on top of the one that shows everything.

A bunch of times now I've missed notes written by those of you I really care about.

It could be as simple as me selecting a couple users that I want to see EVERY note they post. This data could pretty easily be stored locally on each individual client so the way we interact with the protocol doesn't change, and only people who like that feature could use that client.

Or maybe this sounds terrible to you, the free market will decide!
