Our previous data source for inbound link statistics is no longer available, so we've switched to using a new and more stable source for this data, Yahoo's Site Explorer Inbound Links API. The new Yahoo inbound link numbers seem reasonable and still show frameworks we know are popular having high scores, but they do differ enough from the old numbers that they have affected the rankings, so for instance CodeIgniter now outranks Ruby on Rails. This is a good reminder that these statistics are not the absolute truth when it comes to popularity, but rather are general indicators of popularity that can help you figure out what frameworks might be interesting to check out.
