The Zolton.org Social Plugin (ZOSP) is a simple plugin for WordPress that 
integrates a blog with popular social networking sites such as Facebook and 
Twitter. I wrote this plugin to learn WordPress plugin development, and as a 
means to decouple these social networking features from my desired WordPress 
theme.
