TunkRank is a tool for measuring influence on Twitter. A feed's influence depends not only the number of followers it has, but on the amount of attention all of its followers can give. The amount of attention a follower can give is spread out among all the feeds they follow. The more feeds someone follows, the less attention they can give each one. TunkRank's influence measurements can be accessed programmatically using REST calls issued in either XML or JSON format.
