This past Monday, May 1st, 2006, Microsoft published 2 new sites that are great resource sites for developers and IT Pro's.  As I was reviewing my mail and blog (now integrated in one cool interface in my Outlook 2007), I saw Luke's recent post about these new content sites.  The BizTalk Developer Center has been completely redesigned and it is much easier to find what you are looking for (samples, docs, etc).    The BizTalk Technology Center is more broadly focused at IT Pro's who are involved in deployment and management with some great virtual lab resources.  Check out these sites!
