I have updated the BizTalk Bloggers OPML file. This update adds about 6 new BizTalk related blogs bringing the total to 97.
You can download the OPML file here.
If you do not want to track the blogs yourself, you can see most of them online on our syndicated blog site. Currently, Community Server does not support ATOM feeds. So the blogs that only have ATOM feeds will not show up.
