title: Twitter like DB lookup's in mongoDB
body: <p>I'm planning to use mongoDB for a twitter like app. Where you can get all the messages from people you follow.</p>
  
  <p>The best I can come up with is something like this:</p>
  
  <pre><code>Collections:
  Users
  Following
  Messages
  </code></pre>
  
  <p>Every time you refresh your feed you will have to get a list of who you follow. Then query Messages with an array of everyone maybe 1000 id's.</p>
  
  <p>Is there a better way to do this? Would I be better of using a relational database?</p>
