Social networking continues to grow and evolve, expanding beyond the early adopters to attract usage in a wide variety of social, business and educational contexts. Community innovations such as the Twitter ‘hash tag’ demonstrate users’ desire to bring structure to their interactions with these networks, and a plethora of mashups make use of APIs to demonstrate the value of this structure. As yet more structure is added, and as the semantic richness grows, do these networks continue to become more powerful or does increased complexity run counter to the ways in which they are actually used?

This panel will explore some of the issues raised when users and third parties invest effort in bringing structure to their social networks, and will ask what the mainstream social networking sites might learn from – or teach – the likes of Twine and BomedExperts.
