There are many Facebook apps which facilitate the publishing of their posts on fan pages and profiles but most really do not work that well. After much trial and error the most user friendly WordPress Plugin I have found for Facebook is Simple Facebook Connect. Here are some of the feature of Simple Facebook Connect: Enables your site to connect to Facebook with JS SDK Implements OpenGraph tags entirely automatically Comment using Facebook credentials (with Facebook avatar support) Automatically Publish new posts to Facebook Profile or Application or Fan Page Manually Publish posts to FB Profile or Application or Fan Page Integrate comments made on Facebook back into your own site Login with your Facebook credentials optionally using Facebook avatars instead of Gravatars New user registration with Facebook credentials (using the Facebook Registration Authentication system) Facebook Photo Album integration in the Media uploader Like Button and shortcode User Status Widget and shortcode Live Stream Widget and shortcode Fan Box Widget and shortcode Fan Count Chicklet and Widget Activity Feed Widget Share button and Shortcode (reworked version of Like button as Share button is no longer supported by Facebook)
