but how do we cross-check & cross-verify comments & opinions across various web/media/news outlets? for example if this current challenge info is posted/covered on reddit, boing boing, slashdot, hackernews etc.

it would be really beneficial if we could have a unified commenting system that can aggregate feedbacks from all publishing mediums and social-media channels. that in itself could create a single narrative & storyline for each story/news article on a global scale.
