Conversation visualisations

Reading through articles that analyze online conversations I found that next to well known social network analysis there are also several other ways to visualize and through visualisation analyse online conversations.

Turner, Smith, Fisher and Welsher (2005) is a good example article where they use several different methods to visualize Usenet conversations (in time period from 2000 to 2004).

First is a method called Treemaps developed by Shneiderman.
Basically (if I understood it correctly) it transposes large trees into a smaller visualization - a box containing large numbers of boxes. Turner et al. (2005) used this method to depict hierarchies in Usenet according to two variables (thus two different sets of boxes):
-number of posts within a hierarchy (and within it newsgroups, threads),
-number of replies within a hierarchy

Similarly this method could be applied to visualization of conversations on globalism or similar issues on YouTube (the only problem is, that I have no idea how to employ it).

An interesting employment of Treemaps is Veskamp's Newsmap where he creates a program that instantly visualizes current Google news according to type of news (e.g world, national, sports etc.) and for 11 different nations.

Turkish ban on YouTube lifted

The Guardian:

Turkish court lifts YouTube ban after online censorship protest

1. More and more cases of state censorship of YouTube posts are yet another case against optimistic claims regarding YouTube's potential for being a true Habermasian public sphere - free of political (and economic) restraints.

2. This case also shows (yet again) that states are not powerless in the globalized internet world.

3 On a bit more optimistic side, however, this case shows that there is a chance for civic actors to mobilize enough supporters and organize online protest tactics which seem to be working against online censorship of the state.
