Jeff Weber has posted an open letter to Microsoft regarding the Silverlight game development community.
I am pretty confident the Silverlight game development community will quickly grow to become as large(or larger, if the Flash game dev community is any indication) as the XNA game development community.
For this reason, I hereby request, on behalf of all the future and present Silverlight game developers, an awesome Silverlight game development portal along the lines of what exists for the XNA Creators Club Online community.
