I've just wrapped up my last events for MSDN Events until August. In typical fashion, after presenting that content for 2 months, I'm still discovering useful related resources. Take, for example, the workspaces on GotDotNet. These provide a way for you to share information about a product or technology, including bug reports, updates, discussion, etc. I found workspaces there for all of the Application Blocks we recently presented, and I've listed them below.
Take a look at them for tips as well as lively debates!
