The goal: get the world's smartest hackers thinking about how news organizations can harness the open web. The current challenge is all about comment threads. This seems like the perfect question to pose to Slashdotters: how would you foster more dynamic spaces for online news discussion? How would you preserve the context of online discussions and stamp out trolls? All ideas, technical, practical or impractical are welcome. What technologies (federation, atomic commenting, moderation, algorithms) would you employ? What are the immutable social dynamics? Knight and Mozilla will work with the best challenge entrants to deploy the solutions in newsrooms at Al Jazeera English, the BBC, boston.com, The Guardian, and Zeit Online. Submissions are open until May 22nd."
