Google rewrites its search rankings to bury fake news

Google isn't planning to rid fake news from its search results - but it's trying to purge it from the top.The Alphabet Inc. company is making a rare, sweeping change to the algorithm behind its powerful search engine to demote misleading, false and offensive articles online. Google is also setting new rules encouraging its "raters" - the 10,000-plus staff that assess search results - to flag web pages that host hoaxes, conspiracy theories and what the company calls "low-quality" content.Good - but also possibly incredibly dangerous.
