Twitter's Other Ecosystem: Twitter-derived APIs Double in One Year

Last April we wrote about How Twitter's 1 API Gave Birth to 43 New APIs. One year later, there are now 86 Twitter-derived APIs in our directory. The growth of Twitter-based APIs outpaced Twitter mashups, an area we also saw a lot of growth. There are now nearly 600 Twitter mashups. It wasn't even a year ago that we marked the 400 Twitter mashup milestone.

A number of the new APIs focus on making sense from the vast amount of information available on Twitter and share it, such as what the Topsy API does with providing a more complete Twitter search. Others, like the Qwerly API, are connecting the dots between Twitter and other services.
