The sql-server.opml.xml file above contains the list of blogs I follow. If you use an RSS reader like Feedly, you can download that OPML file, then import it into Feedly to follow those blogs.
There are over 200 blogs in the list, but don't be intimidated - just mark all as read after you import, and then try to keep up from there. A lot of the blogs are older and no longer active.
