Joseph Lichterman, writing for Nieman Lab: Two weeks ago, NRKbeta, the tech vertical of the Norwegian public broadcaster NRK, published an explainer about a proposed new digital surveillance law in the country. Digital security is a controversial topic, and the conversation around security issues can become heated. But the conversation in the comments of the article was respectful and productive: Commenters shared links to books and other research, asked clarifying questions, and offered constructive feedback. The team at NRKbeta attributes the civil tenor of its comments to a feature it introduced last month. On some stories, potential commenters are now required to answer three basic multiple-choice questions about the article before they're allowed to post a comment. The goal is to ensure that the commenters have actually read the story before they discuss it.
