Microsoft has created a blog about Windows 8

Microsoft has created a blog Building Windows 8, which will publish an “inside look” from the Windows 8 development team. The blog can be read in eight languages, and there is Russian.
Stephen Sinofsky wrote the first post in which he shared his thoughts on the development of Windows and encouraged users and developers to engage in dialogue with the development team.
