Jon is most at home spelunking, trying to figure out how things work from the inside out. Jon is the author of RESTful.NET from O'Reilly, as well as Essential ASP for Addison-Wesley, and was a co-author of Mastering Visual Studio.NET for O'Reilly. Jon's current major interest is helping people to understand the advantages of REST, but he sees a bright future for modeling as a way to build complex systems. He's a Microsoft MVP, and writes and teaches courses for Pluralsight (http://www.pluralsight.com/). You can read Jon's blog athttp://www.rest-ful.net/.
