Jon Skeet, Author of C# in Depth, Stack Overflow addict
Jon Skeet is a C# expert and community leader, although he has spent most of his career alternating between Java and .NET according to employers' whims. He's currently working in Java at Google's London office, but his preferred language is still C#. His 20% projects at Google include porting Protocol Buffers and the Google Wave Robot API to .NET. He enjoys writing about coding almost as much as the coding itself, and he's currently working on the second edition of "C# in Depth" (Manning, 2008) to incorporate the new features of C# 4. At the moment, Jon is probably best known for his contributions to Stack Overflow, the Q&A site for developers. Jon has been awarded as a Microsoft C# MVP (Most Valuable Professional) since 2003.
