That sounds like a step backwards to me. The problem we seem to be seeing just now is lots of echo chambers have formed without input from "the other side of teh argument" on Facebook, Twitter, whatever social media you choose. What you are suggesting is rather than group level echo chambers which will validate maybe 80% of your views and go against maybe 20%, you are now going to have a fully customized echo chamber that echos your views 100%. I think that will make things worse. Personally I try to get views from both sides, but I think I am in a minority for doing this.
