As a business user, I should be able to make private posts only seen by followers.

When creating a post, it should have the option to be private, meaning it only shows up on the feeds of followers.

Questions:

What is the difference between private and public posts? What level of functionality can we add post visibility to in order to cause the least damage? Is this only for business users? What are the documentation guidelines? What are the testing guidelines?

Tests:

Checking if followers can see the posts Checking if non-followers can see the posts Checking if the post is getting correctly marked as private Checking that people who follow after the post was made can see it Checking if the post creator has the ability to see the post
