Can a healthy political system exist in Internet times?

Alternet seems skeptical, and quotes "MAGIC AND LOSS" (thank you!). 

"Under these circumstances, a healthy political system cannot really exist. I am not sure healthy individuals can either. Heffernan goes on to say that in this digital age of non-stop communication, “we’re all more alone than ever.” That may be the most profound and enduring effect of the media on our politics. We are now so divided we may not be able to unite; we are so divided we live within an aching metaphysical malaise of unconnectedness. We have more “friends” than ever, but feel more friendless."
