We are continuing to explore cool ways to keep everyone up to date -- one new great outbound model are regular newsletters created by the product teams discussing what is going on.
We have two great places, one for ServerFx ("Atlas", ASP.NET, etc.) and ClientFx (Winforms, composiite applications, and a handful of other Client framework related things)
Visit, read, and signup (try Squeet.com to hook the RSS up to your email)
