In case you have for some unfathomable reason missed the posts by Brian, Jon, Mick, Richard Steef-Jan and Yossi, I would also like to point you to the recently launched Windows Server AppFabric CAT Team Blog. It combines posts from some of the most talented people out there, sharing their experiences with technologies from the Microsoft application platform like BizTalk Server and Windows Server AppFabric. If you are still reading this and haven’t bookmarked/added it to your RSS feeds I am very disappointed
