Widget on WordPress Not Showing Content

I installed your plugin, activated it, changed the settings, and placed the widget on my sidebar at http://roundhousetalk.com. The box shows up but I can’t get any content to show up even though I set up 11 people to follow. On the Twitter account side, I created the account. What am I doing wrong?
