As a matter of fact, I wanna have detailed list of how the stuff are shared on Facebook. I mean, you can browse a list of people who publicly shared a post or photo of a fan page, and know who has shared it and when, and how many likes and comments it received after sharing, and read the text attached to the shared item.
For example, this is a sample of these detailed data.
Although there are easy ways to extract comments and likes of a specific post, I could not find any practicable ways to retrieve these sorts of share data using the API. The only way (which is much dirty) is explained here.
Note that the simple number of shares is not sufficient, there are much more data needed.
By the way, I'm a newbie dealing with Facebook Graph API, hence, I would appreciate if you give the http GET commands.
Thanks in advance.
