I’m a big fan of having machines help us with the lower level tasks, freeing up time, resources and brain power for more interesting and complex tasks. Julia [the artificial intelligence system that HuffPo owns] takes that a few steps further and helps us with a lot of other aspects of HuffPost in addition to helping weed out abusive members, including identifying intelligent conversations for promotion, and content that is a mismatch for our advertisers. She has allowed us to do a lot more with a lot less.

I believe that it is useful to be reminded bluntly that the dark forces are out there and that it is too easy to forget that truth by imposing rules that obscure it. As Oscar Wilde wrote in a different context, "Man is least in himself when he talks in his own person. Give him a mask, and he will tell you the truth."

Too many of us like to think that we have made great progress in human relations and that little remains to be done. Unmoderated comments provide an antidote to such ridiculous conclusions. It's not like the rest of us don't know those words and hear them occasionally, depending on where we choose to tread, but most of us don't want to have to confront them.

I have come to think that online comments are a terrific addition to the conversation and that journalists need to take them seriously. Comments provide a forum for readers to complain about what they see as unfairness or inaccuracy in an article (and too often they have a point), to talk to each other (sometimes in an uncivilized manner) and, yes, to bloviate....

In fact, comment strings are often self-correcting and provide informative exchanges. If somebody says something ridiculous, somebody else will challenge it. And there is wit.... Comments also tell us that readers do not always agree with journalists about what is important.
