About the Technology: The eXtreme Programming (XP) movement started six years ago, and since then it has gained momentum and maturity: XP mailing lists continue to generate heavy traffic, with an estimate of regular participants at 3000. A number of conferences have been started, focusing on eXtreme Programming and other agile methods (in addition to conferences such as OOPSLA, where it is covered extensively), and attendance is ranging from 3000 to 5000 per conference.
