title: Can 2 Relationships be related in an ER Diagram?
body: <p>I am designing an ER for a Dummy Social Networking site where I need to relate 2 Relationships . Specifically, as per the diagram attached, I am relating Posts relation and Followed By (Followers) relation with a new relation 'can see'. </p>
  
  <p>That is, Followers can see Posts of the user they follow. I need Posts because it will have the UserID of the user who posted Blip with BlipID. Diagram is not complete yet, so ignore Participants, constraints etc. 
  Any suggestions on this, please?</p>
