I have uploaded an update to the BizTalkGurus.com BizTalk Bloggers OPML file. This update adds 6 new BizTalk related blogs and brings 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 the blog content online on the syndicated blog site. Currently, Community Server does not support ATOM feeds. So the blogs that only have ATOM feeds will not show up. Too bad since some of the best BizTalk blogs are on Blogger.
