Firstly, last years developer competition was so much fun we are doing it again but bigger. This time in conjunction with SQL Server 2005 and Visual Studio.NET there is a joint connected systems developer competition. The top prize is only $50,000. Check out the details here.
Secondly, I've always wanted to do this, yes always. For 2000, 2002 and 2004. I just never got there. Finally I'm going to do it! (thanks to a big push from Jeff on my team). To warm you up for TechEd I will be posting detailed BizTalk Server 2006 feature documents to my blog over the next month or so. Look for the first article early next week and then regularly until TechEd. Every week you'll get a glimpse into additional areas of the product including setup,migration, development, administration and business activity monitoring.
In other news thanks to Aaron S from Pluralsight for setting up the BizTalk kiwi - I mean wiki :). Check it out here.
