title: Best solution for a comment table for multiple content types
body: <p>I'm currently designing a comments table for a site I'm building. Users will be able to upload images, link videos and add audio files to the profile.</p>
  
  <p>Each of these types of content must be commentable. Now I'm wondering what's the best approach to this.</p>
  
  <p>My current options are:</p>
  
  <ol>
  <li><p>to have one big comments table and a link tables for every content type (comments_videos, ...) with comment_id and _id.</p></li>
  <li><p>to have comments separated by the type of content their for. So each type of content would have his own comments table with the comments for that type.</p></li>
  </ol>
