Interesting an thought provoking article.
One big concern I have with radical transparency that I did not see addressed in the article or in the comments (I did not read all) is violence coming from the crowd. While libertarians might be cool with minority positions even if they disagree with them, this is not true for all other ideological groups. The article mentioned needing a certain faith in the goodness of man. Even if you assume people are well intentioned, they still have different ideas of what "good" means.
Even if what I wrote is correct it does not mean radical transparency is a bad approach, it just means that on its own it is not sufficient.
