This is a site that appears to have been started by the MS folks to help distribute SharePoint Related information, Web Parts, Templates, etc... some good stuff there.

We are really starting to see alot coming out of MS built on top of SharePoint. When I was at Tech-Ed, I really complained about the lack of Reference implementations, Web parts and community for the developers of SharePoint Technologies. It looks like Microsoft is making some strides in two out of the three (there is still no forum supported by MS.. only the newsgroups and google doesn't find info in the newsgroups too well IMHO) Two out of three ain't bad ;-)
