Certainly social networking sites like Facebook are opening pathways between diverse and disparate people, flooding the marketplace of ideas with new remixes, collaborations, and possibilities. We can think of it as akin to the introduction of the novel, another historical turning point that had the masses interested in the movements of strangers. At the turn of the century, people were able and willing to use novels to move private information into the public realm, and now, a decade removed from the turn of the millennium, we are eager to draw the blanket of public space over our entire private lives.

Pictures, messages, and replies that would go too far or be too mean to shout in a public square, are commonplace on the web. Where does the shift from "private" to "public" cease? Or on the other hand, will we as humans continue to welcome technological advances that further the public broadcast of our private lives?
