As you will see from his site here: http://paulschreiber.com/blog/2011/02/11/how-to-display-tweets-on-a-wordpress-page/, great idea with a great start. Connects to Twitter API and outputs simple html giving devs the reigns to style away. Problem is, after you reload you'll notice things are broken. Caching is necessary because of API rate limits, but caching doesn't work. Developer keeps commenting the same comment to users when apparently that is not the solution (hasn't worked for anyone yet). Chances are dev has given up on this project, sad though because it was exactly what I needed and will easily come back to it once this is fixed.
It appears that WordPress has built in caching capability that the dev is not using, rather is making his own file caching for unknown reasons. Good luck finding another solution for now at least.
