The route of community building is interesting and I can see many people following that. If you see the latest development at Biz Stone's Jelly, their vision is to make a trust score on users and build credibility. The challenge is how quick a community can respond. Fake news is growing like the snowball effect the more it spread on the social media the more it becomes a problem. We need to put a filter before we share the news inside our network - like a verified posting :)
