title: Do services other than Facebook use Open Graph?
body: <p>Will other services other than Facebook use Open Graph tags when scraping the page for sharing information?</p>
  
  <p>Meaning, if I have an AddThis button (for example) on a page, which allows sharing to Facebook, Google+, and Pinterest etc., will any of the other services also honor those meta tags? Or is generally something we do specifically for Facebook?</p>
