Right, but that doesn’t automatically mean that Redditors have better reputations. I use Reddit daily, but if I see any news that might sound absurd, I will definitely take a look on other news sites to see if the information is real. Journalists, impartial or not, may at least have better credibility in these news sites.
Have you seen the reputations of most "journalists" these days? Several UK newspapers frequently repost stories from forums like reddit and mumsnet.
