I mentioned already that you cannot having any kind of viable voting system or useful sentiment from which to analyze if you do not have a means of anonymous participation. You can't do any sort of valuable research in areas like anthropology, or understand the current moods, opinions, thoughts, of the population, because you will never know what anyone really thinks unless you give people a means of providing sentiment.

How would you even do something as simple as a survey without anonymous participation? Even if I'm the one asking for the survey would I want people who might be afraid of being downvoted or some sort of enforced accountability if they answer my survey questions in a way I don't like? I can't become better or improve what I'm doing if I can't get anonymous statistics.
