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.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
