Facebook API

https://developers.facebook.com

Facebook for developers

Comments from the Facebook site.
The advantages are that all comments are together. So they can be seen from any page.

Minus - a comment can be left by a person registered with Facebook.

Unfortunately, the section of the site on the API is constantly changing and it's not always easy to find the right one. Moreover, not all speak English.
So I spread the code:

Code

<div id='fb-root'></div>
<script src='https://connect.facebook.net/en_US/all.js#appId=APP_ID&xfbml=1'></script>
<fb:comments href='www.ph4.ru' num_posts='5' width='560'></fb:comments>

Here is:

1. www.ph4.ru - our site, Change to your,
2. num_posts='5' - the number of posts displayed, we have 5,
3. width='560' - width of the block, change to Your design.

Facebook has perhaps the greatest opportunity to integrate Facebook functions into your site and vice versa (creating your own applications for Facebook).
