"Sometimes it feels like the list of friends on the social network site stretches in eternity. Everyone always turns out to have some sort of connection to everyone else; six degrees of separation. There is immense potential in digitally mediated friendships, but it is only when these are materialized in the post-digital - when selection becomes a pressing issue - that friendships can be said to happen. There are no physical rooms with room enough for unlimited number of bodies. Being physically present does not allow for tabbing to the next chat window in order to get away from a tedious conversation. You might choose to leave, to go somewhere else and strike up a new conversation there. This is still not the same as typing into a new blank chat window, because there is an already existing situational context we must take into consideration before we act."
