An interesting application/plugin for WordPress is WPBook. This plugin installs on you blog allows your post to be visible on a Facebook page. It only works on self hosted WordPress installs.
The installation is, from my experience of WordPress plugins, a little quirky. This is primarily because the WPBook requires that you create a Facebook application. This sort of thing is a little daunting for someone like me with no programming experience. However it is really more about creating the application within the developers section of Facebook, this creates an API key and another password or key called a secret. You then enter theses details in the plugin section of your blog. You need to give your application a unique name so that it has a “canvas” name this is Facebook jargon for where they host their application. So after a few trials and errors I was able to create an application that now displays my deep and meaningful post on my Facebook page.
