Discourse has devolved so much it is going to be tough getting people to debate respectfully around different viewpoints. It might be better to recruit a handful of people who can set the tone for these debates and then eventually open it up for a larger community.<p>I agree with your sentiment about publications just rehashing the same story. That's a large reason why I started <a href="http://emergentdata.co" rel="nofollow">http://emergentdata.co</a>. It's not political focused rather focuses on technological acceleration and large global issues like water scarcity and mass migration. I try to curate content around a few principles:
-Try to get to the most original source
-Stick to real events, avoid speculation and hearsay
-Avoid sensationalist headlines<p>Good luck to you.<p>Edit: typo
