If you are thinking about the system of commenting your site, you should look at our widget. It allows you to comment on articles not only as an address, but also to the article as content. Our widget recognizes the unique content and finds the discussion for it.
Discussion of the article or other content will be united around the world. If you have a few comments on the site with the conventional system comments, you should set this widget, and the number of comments will increase more than twice.
