I did my presentation on the CHI 2008 paper, "Friends and Foes: Ideological social networking" by Michael J. Brzozowski, Tad Hogg, and Gabor Szabo. This paper was as a replacement for the previous UIST 2008 paper's presentation.
The paper essentially did a study of the web site Essembly.com which is, according the authors, "a 'fiercely non-partisan social network' that allows members to post resolves reflecting controversial opinions, e.g. 'Overall, free trade is good for American workers.'" That said, it was similar to the social networking sites Facebook and MySpace, among others. With the social connections, there was a difference in that there were friends, allies, and nemeses on voted upon issues. Their findings were as follows:
In the end, the paper was a reaffirmation of previously held thoughts: (a) that the nemesis type wouldn't be implemented, (b) that there was little voting accept on that of friends, and (c) the allies feature was hardly used.
