I also don't have the skills for building such a thing. But if I could help with such a project through testing/QA, or contributing to a website, or gathering resources - whatever, really - I would, and I would use it. I've been thinking a lot about confirmation bias and echo chambers lately, too, and the truth is I don't know exactly where to look for opposing viewpoints all the time, and it's hard to gather the courage to just dive in when I know a good amount of it will make me feel ill. Maybe just starting with a collection of opposing resources? There could be a call to action to ask people to submit articles or sources for various "stances" on different topics, and a list divided by topics and view points, or links to the few sane and awesome discussions you can occasionally find where people who think differently actually talk to each other about their differences like rational human beings. That might be an approachable place to start, anyway.
