Mr. Fahey, I agree completely that interests for all people that a person connects with on one service will easily move to another service. I have been ranting on the granular social network for years and should reflect in any social portability, but that is a tougher nut to crack.Related to what people do in social software (I roll the web services into social software, but it can also me mobile based like Jaiku or Radar (from Tiny Pitures)) are a larger set of actions and patterns around social software and related services, see http://flickr.com/photos/vanderwal/2049590133/ (a blog post will be coming on this at some point).I am finding that (stereotype follows) those under 30 are actually using the services that those over 30 are just using for friending. The size of the groups seems to depend on where people are geographically and their culture. But, the highest levels of service use are with groups that are 6 to 15 people, but many individuals belong to more than just one group and service. Those with over 100 connections are not the norm, which are those most interested in social group portability. But, many who have far fewer connections in their social groups are also stating and prefering to use services that allow them to interact with their friends and connections. Many of the 30 and under set say they know who their friends are that they want to keep and have with them on a service. Services finding that they can lower the rebuilding those connections and let the people try and use their service find greater adoption and longer lasting use of the service than before they had those capabilities.Saying people like friending, but people are not staying with services that adhere to that view.
