In the past, the product team has been blogging about BizTalk in multiple blogs:
Over time, some of these have become silent and others are updated from time to time. We’ve also heard that it is confusing to look for related information in multiple places. To solve this, we’re going to consolidate all BizTalk product team blogging into this blog: http://blogs.msdn.com/biztalk_server_team_blog/
We’ll try to make our blogging more interactive – we’ll respond to comments on articles and ask for your input on features you use and topics you want to hear. We’ll periodically post articles, so keep in touch.
