"Make all users post under real names that you verify". Advantages: * Better comment quality: verified users would think twice if they wanted a curse words to show up when someone googled their name. * Connectivity: If you like someone's reasoning and thinking, it would be easier to check out more about what they do online (accomplishments, blogs, twitter, etc). Disadvantages, anyone?
1) The Internet never forgets. If you post something regretful in a fit of rage you can never take it back. You are not the same person you were ten years ago (even if you have the same name). Do you want to be judged today on how that person behaved back then? It is naive to think you won't be judged so. 2) There are some really batsh*t-crazy people in the world. I prefer to be somewhat isolated from them. 3) How do…
That said, I don't think this is necessarily something where solid evidence matters. It seems to me that requiring real names is much more about making bloggers and journalists who consistently have their real names attached to postings feel more on an even footing with their commentariat. See, for example, this post on crosscut where Ted Van Dyk argues that he feels more comfortable with a critic that has a real name attached: http://crosscut.com/blog/crosscut/19530/Should-online-commen... Is that about categorical differences in comment quality, or personal comfort within a newsroom?
