Over at The Pensive Gamer I've started a Developer Diary concentrating on exploring XNA.
The first Developer Diary describes how to get started in XNA. Includes useful tools, community sites and blogs related to XNA.
Here is a snippet from the article:
Each week I like to set aside a few hours to explore software development technologies I haven't tried. This past weekend I started to take a deeper look at XNA.
I'll be documenting my XNA investigation with periodic updates as a Developer Diary. Today's Developer Diary is simple, I documented what I did to get a base understanding of XNA.
I'm also curious to hear of any other tutorials or tools people have found valuable for XNA development.
