@betomoedano did basically this in my social media app too, vote and favorite right from the notification, no app open, just expo-notifications categories doing the work.
i built a social media app, entirely on @expo.
but it's the opposite of a feed. it's shaped like a dictionary, every topic gets one page, and everyone writes the definitions.
no feed, no algorithm, no follower counts. you read what people actually think about a thing, all in one place, instead of watching it scroll past.
