title: How can I check if a facebook like button has been clicked?
body: <p>I've put facebook like buttons into my wordpress blog... the idea is to use them as kind of a voting mechanism for posts. What I would like to do is automatically add a comment for the blog post everytime someone 'likes' it via the facebook like button.</p>
  
  <p>So my question is- does the like button api provide some kind of a callback to my page if someone 'successfully' likes something? - ie. they have not already liked it before, and they get through the process of submitting it to facebook successfully.</p>
  
  <p>Thanks for any help. Fyi I am very new to the facebook api</p>
