title: Is it better to store all comments for everything in one table or have multiple tables?
body: <p>Lets say you have 3 or 4 site features like photos, videos, wall posts, etc.  And each have the ability for you to leave a comment.  </p>
  
  <p>Should the DB have 1 table and insert all those comments in that one table with their respective unique IDs or should they have like 3 or 4 other tables like Photo_table, video_table, etc....</p>
