Building on a growing base of semantic web technologies this service is another clear pointer to the direction the Internet is taking, with markup focussed on meaning rather than presentation, and applications able to work with and augment each others data as a matter of course. The API will affect social networks, who will need to choose the level of openness they are willing to support.

Though the system uses only public data, the power to query and analyze could affect the way you choose to present yourself online. It could also lead to some interesting situations where connected people perceive different qualities in their relationships. It’s not just how you link to your friends, it’s how they link to you. Are your ears burning?
