From what I gather


objects - things that you talk about
   has a URL to lead to them
actions
 - Your interaction with the object

you have to login with facebook credentials. Then I suppose you publish that object/action pair. Assuming the URL is the same for the world you have conversations on that objects along with various actions.

So..


Object
  action - by an actor
    conversations - by other actors
