title: Determine if a visitor has liked/followed a third-party?
body: <p>If you already Follow a company on Twitter, then that company's "Follow Us" button automatically greys out (regardless of the domain), so:</p>
  
  <p>Let's say you have the Twitter handle of companies A, B, and C ... is it possible/what would it take for you to determine if User-X is following A, B, and/or C?</p>
  
  <p>Same deal for Facebook "Likes".</p>
  
  <p>I'm most curious if there is a way to do this WITHOUT requiring the user to give oAuth permissions (e.g. have them "Connect with Facebook").</p>
  
  <p>Thank you!</p>
