IT Analysis - All Alone in a Social World?
At a base level, one has the problems of just interacting between similar social networking sites, for example, enabling one person on one wiki to exchange information with all other wikis at the same time. Recently, there has been an explosion in aggregation sites, particularly around blogging, enabling activities and events that happen on multiple sites to be reflected via the aggregating site. However, each different type of social networking site does tend to have its own "Vocabulary" - sending someone a "Hug" on FaceBook is difficult at this stage to represent to a person using LinkedIn, for example. Further up the scale one has the problems of how different types of site interact with each other.
