title: How to refresh the cached title of a page Liked on Facebook?
body: <p>I have a couple of embedded YouTube videos which I have added Like buttons for.  The titles were wrong the first time I tested the Like functionality.</p>
  
  <p>Although the video titles have now been changed, the old titles are still showing up in a user's news feed when they click Like.</p>
  
  <p>Is there a way to get Facebook to get the new titles of the page, or are the titles now cached forever?</p>
