This is a good plugin if you want to keep your site up to date with your (or any) latest Facebook posts. The Facebook API is notoriously slow but Recent Facebook Posts caches the posts so that it doesn't delay pageloading. The plugin works well, is easy to implement and easy to style with CSS so you can make it look the way you want.
The author is constantly improving the plugin, ironing out little glitches that users report in the support threads. So try it out and don't forget to donate if you find the plugin usefull.
