Man with no Blog

A good 12 months ago you could depend upon a a solid core of your social network to be centralised on several common social networking sites, such as flickr, twitter, facebook, linkedin. Things where relatively stable, well as much as they can be. Comments on one sns stayed on that sns, comments on a blog, stayed on the blog. The core of the sns mob would from time to time go explore a new sns, sometimes integrating it into the group of core sites sometime not.
