New plugin for comments

One of the “secrets” of Facebook’s success is its tools for integration with other sites, since they “lead” more content (or links to it) on Facebook, which in turn turns Facebook from a regular social network into a powerful platform, which users can use in a variety of ways.
Among such tools, plug-ins play an important role for media sites of news agencies, newspapers, television channels and the online publications themselves. Plugins allow people to easily post links to articles they are interested in on their Facebook wall and comment on them using their Facebook name instead of registering on each site separately.
Recently, the media comment plugin has undergone minor changes that should be borne in mind by both publishers and users:

• Comments in the plugin are displayed taking into account user relations and commentators and the quality of comments: comments from friends and friends of a user and comments and threads with the most answers and "likes" go up to the plugin.
• Next to the name of the commentator indicates public information from his profile: age, city of residence, where he works, the number of mutual friends.
• The discussion that begins on the site can be continued in the user's Facebook feed: all comments left under the Facebook article are synchronized with the comments in the plugin on the site, which allows you to save a single discussion on the site and on Facebook. If someone responds to the user's comment on the site, the user will receive a notification on Facebook.
• Users can comment not only under their personal profile, but also in page mode, if the user comments in the plugin in page mode, then this comment will be visible to all fans of the page.
• All comments in the plugin and on Facebook are now organized into discussion threads.

Also, the changes affected the moderation of the discussion:

• Moderators can make a list of words that can not appear in the comments on the site and also make a black list of users who can not take part in the discussion.
• Moderators can set the mode of pre-moderated comments, all comments that users leave on the site will be visible only to them, their friends on Facebook and moderators. Comments will appear on the site and will be visible to all visitors only after the moderator approves the comment for publication.
