As mentioned, Project Silk looks like a new project by Microsoft Patterns & Practices to provide guidance and sample implementation on building web applications using web technologies like HTML5, CSS3, and jQuery.
Patterns & Practices announced they will be holding a 1 day web workshop on February 25, 2011 for 30 people interested in immersing themselves in those technologies, plus ASP.NET MVC 3! Not only is this probably a great experience for the attendees to learn, but I suspect patterns & practices will also be seeking your input on what type of guidance they should be including in Project Silk.
The free workshop is a few days before the 2011 Microsoft MVP Global Summit, so this may be a great time for MVPs to kill 2 birds with 1 stone. Space is limited, so I would make your submission for consideration really good :)
