These are my favorite DNA blogs (many are both genealogy and DNA), divided into groups, then listed in order of how often they post. Most of these you can follow by signing up for an email notification. Otherwise you can use one of the many RSS feed services on the web. Personally I use protopage.com to follow most of them but there are many other RSS agregators.
