Steven Sinofsky published a new blog entry, this time discussing the Windows 8 Start screen

We've been having a lot of discussion regarding the two recent posts on the Windows 8 Start experience. Those of you who have used the Developer Preview are contributing to our understanding of your individual usage patterns and what is easier or more difficult than in Windows 7. As a reminder, we released Windows Developer Preview build with the full product "enabled" even though we still had much feature work to do in the user interface. We did this in order to foster the dialog and we want folks to understand that the product is not done. We've seen some small amount of visceral feedback focused on "choice" or "disable"—a natural reaction to change, but perhaps not the best way to have a dialog leading to a new product. We’re going to focus this post on making sure we heard your constructive feedback around the design as we continue to evolve it. Marina Dukhon, a senior program manager lead on the Core Experience team, authored this post focused on specific comments and the actions we are taking based on what you have said.
