Mathew Ingram:

While the Disqus data may not be conclusive, however, it does seem to show that pseudonymous speech doesn’t necessarily lead to worse behavior than any other form of online identity, and may even lead to better behavior (at least for those who see user comments as being valuable at all).

I agree with what this data shows. Some of the best emails I get are from people that don’t wish their name or company to ever be known. My best guess as to why: people at great companies or in a position of great influence within a sector are very smart — these are, I think, the same people that have great insight to add through emails that I receive.
