Facebook like button and comments, how to get users?

I have read a lot of stuff about the Open Graph Protocol and Social plugins.

But I'd like to know if there is a way to programmatically retreive the full list of facebook users who "likes" or "comments" my pages.

For example, imagine that i am the webmaster of http://canalstreet.canalplus.fr/musique/live/canal-street-l-emis开发者_JS百科sion-du-05-03-hocus-pocus-en-live-beautiful-losers and i would like to manage people who used the facebook comment block.

Any idea ? It would be interesting.

Yep, just query the "like" table for the object you want to get information about: http://developers.facebook.com/docs/reference/fql/like
