Readwise Feed is an experimental passive social media platform that showcases a number of users' reading activity and interests in a single feed via syncing their activity from Readwise.
It is built with Next.js, Prisma, and Vercel Postgres.

There are two kinds of activity on Readwise: highlights and bookmarking (via the Reader app).
The app fetches the latest highlights and bookmarks from Readwise's API and stores them in a Postgres database. It then fetches the latest highlights and bookmarks from the database and displays them in a feed.
Every 30 minutes, the app syncs the latest highlights and bookmarks from Readwise's API.
The feed works for books, articles, Tweets, podcasts, etc. – anything that can be added to Readwise.
