Responding to a discussion on Flickr and the Future of the Internet Thomas Vander Wal describes on vanderwal.net why social networks are important and how they leverage the ‘Personal InfoCloud’.

Helping to reduct the coming stench of information that is resultant of the over abundance of information in our digital flow. Sifting through the voluminous seas of bytes needs tools that provide some sorting using predictive methods. Amazon’s ratings and that matching to other’s similar patterns as well as those we claim as our friends, family, mentors, etc. will be very important in helping tools predict which information gets our initial attention.

As physical space gets annotated with digital layers we will need some means of quickly sorting through the pile of bytes at the location to get a handful that we can skim through. What better tool than one that leverages our social networks. These networks much get much better than they are currently, possibly using broader categories or tags for our personal relationships as well as means of better ranking extended relationships of others as with some people we consider friends we do not have to go far in their group of friends before we run into those who we really do not want to consider relevant in our life structures.
