Anything we can do to reduce fake news should be welcomed and encouraged. As far as I understand, this could be a powerful tool. Wouldn't it cause some delays in new delivery though? It also seems like it's meant to be a separate platform. This would mean that many people will still be going to the same news sources as they always have. They will continue to get fake news because they are ignorant of the new tools available. The idea may be great, but the biggest challenge may be implementation.
