On the Developer Drive site there's a tutorial posted showing how to create a dynamic auto-ranking Twitter list in a WordPress-based application.

My team and I recently built an awesome list template on WordPress that ranks a set of Twitter users based on follower count. It allows a content writer to easily add a list of Twitter handles, and generate a well designed post.

They start with a list of requirements the end result needs to meet including the Twitter information, features it should offer and the resulting output. The rest of the post walks you through every step of the process to get the system set up including:

• installing the Advanced Custom Fields Pro WordPress plugin
• Showing an "infinite list" in WordPress
• Code to loop through the Twitter data
• using the TwitterAPIExchange PHP library to get Twitter data

All code and steps you'll need to make the system work are included and they've posted a demo so you can see the result first hand.
