Doug has an update on his blog on "What is Codezone really"? As the conceptual look shows: Codezone is about connecting not integrating!
More about "community content" on Marie's blog. She explains the searching and installation (end-to-end) for a project template from the community in the Visual Studio 2005 Beta 2 release. Also other components such as Item Templates, Code Snippets, Controls, Add-Ins, Project Templates,... could be found and installed for use from within your develeopment IDE. So, in a few months almost everything could be integrated in Visual Studio: IM integration, RSS Feeds, blogging support, newsgroups access, ... Add to this the Visual Studio 2005 Team System functionalities and Team Foundation, and the Visual Studio 2005 IDE will be "the" communication environment for all day work!
