On leap day 2012, we (the Windows Engineering) team launched the Windows 8 App Developer Blog!

Post from this blog are all written by the individual engineers who worked on these features. The blog will let you connect with the individuals who brought you Windows 8! Come see how we are using our own features and what tips and tricks we have to share. This blog is dedicated to developers!

I will probably contribute to a post or two to that blog pretty soon. In the mean time, let me know what you’d like to learn about!
