title: Instagram style news feed logic
body: <p>I am in the process of making a social application that involves users and a news feed. In order to display a user's news feed in chronological order, which of the following would make more sense?</p>
  
  <ol>
  <li>Get all posts from each user the person is following and sort them into chronological order</li>
  <li>Each time a user goes to post, save that id and the date into each
  of their followers profile data (seems redundant)</li>
  <li>A better solution that you may know</li>
  </ol>
