I am in 2 minds with this. I really like the idea of a blogging ecosystem that rewards people for their content and interaction but on the flip side the mass appeal will be a more bite size social networking platform. I think one of the reasons G+ failed to retain the users attention (apart from that their friends never left Facebook) was that they tried to be too many things too everyone. Sometimes niche is what you need to complete with the behemoth that is Farcebook.
