Updated Mitch to his latest position, and added XNA content

Mitch is a program manager on the XNA framework team. Previous to this he was (one of?) the guy(s) responsible for Terrarium. He's got several articles about managed DirectX and game development. There was rumor (and a screenshot which has gone) that a future version of Terrarium might have some real 3-d (Managed DirectX?) in it. He also did some 3D work on something called Mantis.

These days he is 100% on the XNA platform and his blog has plenty of good content:

• Game component explanation and template examples
• Game Components demo (from XNA team blog)
