1) opinions masquerading as news. 2) misinterpretation of facts/data. 3) misrepresenting the facts. 4) cherry picking (not showing full picture, such that the meaning changes). 5) insufficient context / history about the topic.
All these issues with reporting could be mitigated with expert + crowd annotation — esp where the author and the subject (say people mentioned in the news) can come and add more context.
When objective function is speed and clicks, sometimes depth on a topic suffers. This is true whether news is human or machine generated. In that case, continual engagement with the original article, amendments and updates become a very important tool.
If journalism is defined as a search for truth, then news annotation could be the thing that saves it.
