Again, Google is trying to get more social. Until today, the only social feature was Following, now this has combined with Google Friend Connect to make blogging even more social. When a follower joins a site, it will show in their Friend connect profile, allowing more and more exposure to blogs. Google decided to add this feature because Following was limited to Blogger sites, now any site (i.e., wordpress) that has Friend Connect can be followed. Note that for blogs that were already using Following, they have been migrated to Friend Connect. I think this is a great feature and is fantastic for the evolution of social networking from a handful of websites to millions.
