I'm trying to get all the comments of a url that was added to facebook. is this possible?
It is possible to get all comments (from Comments social plugin) associated with URL by issuing next request to Graph API:
http://graph.facebook.com/comments?id=URL
For example some article on TechCrunch:
http://graph.facebook.com/comments?id=http%3A%2F%2Ftechcrunch.com%2F2012%2F02%2F27%2Fyahoo-stabs-facebook-in-the-back-says-pay-for-its-patents-or-get-sued%2F
