Have a group of users and want to see who has more followers, who has the most updates or who follows the most people? Well now you can with TwitterLeague. It's really simple, just sign in with your existing Twitter account using the "Sign in with Twitter button" and create your league (or as many leagues as you like). Basically it's about competing in a league with other Twitter users - say, friends - to get the most followers. The leagues can then be put on a site using a snippet of JavaScript or you can get an XML feed to create your own customised look and feel.
