Yeah! I have started development. I am using the latest and greatest in web application development, Ruby on Rails. Ruby on Rails is a great framework for developing highly interactive web applications. It supports all sorts of new technologies like AJAX, RSS, XML and more. The latest slang term for this type of application is a Web 2.0 application. Although this is my 3rd redesign of steptracker.com I can reference it as Steptracker 2.0.
