> only promote things on my feeds that are "liked" by people within a geographic radius of me

Ugh, really? I live in a part of town where I speak a different language than the vast majority of the people in this "geographic radius of me" which means I'd see very little content that I could understand.

Where do people come up with these wild ideas of anything other than show me the content of people I want to see in the order it was posted? If you want a "Feeling Lucky" type of feed, make it available. Otherwise, you're sending people content they don't want and are only too lazy to stop using it.

$trillions of global brainpower is spent yearly trying to answer "How do we get people to consume things they didn't ask for?" whether those things are products, services, ads, or online content.
