Is the socialnetwork killing our sense of self and community?

Are we just all too faced now? With one outwards face to the world exemplified by our facebook page which is often manipulated by us to be our public face but in reality is nothing more than the outward face we project?

In years to come we will lament the lack of public spaces that are privately run such as pubs or will the general feeling be that our online social networks will be enough to sustain us and chance encounter will be a thing of the past.
