In the background, Bit.ly is analyzing all of the pages that its users create shortcuts to using the Open Calais semantic analysis API from Reuters! Calais is something we’ve written about extensively here. Bit.ly will use Calais to determine the general category and specific subjects of all the pages its users create shortcuts to. That information will be freely available to the developer community using XML and JSON APIs as well.
