As of today, WordPress publishers will be able to easily integrate Facebook features through a new Facebook for WordPress plugin. This allows anyone to make their WordPress site more social, and it’s fairly simple too.
Once you’ve installed the plugin, you will be able to post directly to your Facebook Timeline and other Facebook pages you manage. You can also mention friends and pages in your post (this helps distribute your content to a wider audience).
There are numerous social plugins that are available WordPress Widgets, such as an activity feed and a comments box. There are also customizable buttons and a recommendations bar. These can be easily dragged-and-dropped into your site’s sidebars.
