Using Drupal 7. I post some stories on Facebook and receive a lot of comments. I want these comments to also show up on the article page on my drupal site, not just on the Facebook page inside facebook. That is, when users comment on the post inside Facebook, i want the comment to show on the article page on my drupal website. Any ideas in getting this to work?
You can have a look at this Facebook Comments Social Plugin Module
Implement Facebook commenting with settings on the level of both content type and node. This module comes with a Facebook Comments block so you can have comments anywhere on your site.
There are another modules which support your functionalities -> FB Comments Box
This module gives your site the ability of using Facebook's Comments Box social plugin, i.e. comments on your site powered by Facebook. It provides an easy way to configure Facebook Comments parameters (like theme, administrators, number of posts, node types to attach to) and then exposes the generated code as a block for you to insert into a region of your choice. This module is intended for anyone who wants to put Facebook Comments on their Drupal site in addition to or instead of Drupal comments from core.
