To be sure, not all anonymity is bad. Sometimes it allows people to ask questions or make comments that would be awkward or inappropriate if their true identity were known. But such occasions are relatively rare.

This may sound crass, but you really have no idea what you're talking about. I use anonymity all day to push intellectual discourse way ahead of where it normally could go. I am disappointed that you seem to have an extensive understanding of many aspects of internet culture, but fail to recognize the importance of anonymity on the internet and how it has revolutionized how people discuss sensitive issues.
