title: why graph api like count missing
body: <p>Graph API is not reporting number of likes (shares) anymore, or is at least inconstant about it:</p>
  
  <p>Here likes are missing:

  <p>but present on IMDB:

  <p>also old output with number of shares and comments can be found for older web pages.</p>
  
  <p>Is this a problem with roll-out or is this a bug? From what I can gather output started to change around 20th.  </p>
