I\'m currently running into an issue with Facebook\'s realtime API.
I wish to subscribe to a number of things on a users profile, including their \"Likes\" in the Music,
Not exactly the answer, but still ...
Couple of months ago i was given a task to fix a facebook app. It used information provided by facebook to build statistics. But policies changed and facebook stopped providing that info.
I've used graph and fql to obtain that information. Grahp api is pleasant, because you don't have to be registered + the answer is in json format. The main problem is that Graph api is soooooo slow....
Let me give you a hint that helped me: fql is very alike sql, and maybe you should try some functions or other methods which are native to sql.
Who knows!
