Tweeting about things going viral, traffic, and Medium, I decided to check you out on G+ and I noticed you have posted a couple of posts in March 2013 subsequent to your Aug 2011 post. I note you only have 54 people in your circles, maybe you would like me to share one of my large circles with you? But I doubt you will match your high Twitter follower count, 82,889 is very impressive but I am sure you if you had a similar amount of followers on G+ you would see much more user interaction.
On the issue of Medium, I think a Blogger template in a Medium style could be generally much more social than Medium (assuming you have an equal number of followers on G+ compared to your Twitter/medium followers). A Blogger template in a medium style could link up to a G+ community where social interaction is high, for example the Google Help community (https://plus.google.com/communities/115758385206378551362
), which would then allow users to raise the profile of the blogs and interact more socially regarding their blogging, which I think could be far superior to Medium.
