Last week, the YouTube comments section got a facelift. Now, according to the YouTube announcement, commenters must link their accounts to Google+ profiles. Comments will also be listed in order of relevance instead of the most recent first, allowing spammy and unproductive comments to fall to the bottom. The comments section of YouTube is infamous for its outpouring of uncivil commentary -- largely believed to be fueled by anonymity -- but the new policy has inspired widespread controversy. YouTube is not the only digital media outlet that is struggling to find a balance between free and civil speech in its comments section. Many media sites may be worried that comment moderation blurs into censorship; the alternative is a lawless zone of hate speech under the outlet’s digital roof. Joining us to discuss moderation ethics is Mathew Ingram of GigaOm.com, The Huffington Post's Jimmy Soni and Poynter’s Sam Kirkland. Regular guest Andrew Lih of American University will host in Mark Glaser’s absence.
