Social networks are great: you can stay in touch with friends all across the world and find new ones based on your interests. But often, social networks serve a single purpose or interest. For instance photos, videos or classmates from school and university. This is not a problem by itself, but when you want to keep track of all your contacts in all these social networks, this is a lot of work for you to update your contacts list in all the social networks you are in. and you also might need to get a member of a social network, although you're not interesed in the subject, but only want to track your friends activities. NoseRub only defines the social network and some basic content types like media, links, micropublishing and text. You can now add all your contacts to a NoseRub network and aggregate several social networks into just one. and you always have full control of your data, as you can install NoseRub on your own server and have it connect to other servers out there.

As such, Trevithick said data portability would help bring about an Internet of the future where you don’t have to repeat yourself, because your data would exist in cloud that’s accessible whenever and wherever you go online.

For users to have true data portability, there needs to be some consensus on both the APIs and the formats needed to transfer / represent this portable data. It may be that a number of APIs and formats are required for different scenarios. The Semantic Web is an ideal means for representing the data to be ported from social websites, in that is well suited (using vocabularies like SIOC and FOAF) to represent how people and all kinds of objects on these sites are connected together (documents, discussions, meetups, places, interests, media files - whatever). Of course other data formats may be used, but most importantly, it would be a waste of time to come up with a bunch of new formats for representing the data that needs to be portable, because a lot of work has been done on how to best provide interoperable, reusable and linked data through efforts like the Semantic Web, AtomPub and the microformats community.
