I propose journalists should do their own research like the old days, and directly talk to the people in question, then form their own conclusions and report that, instead of just regurgitating third-hand blogspam.
If something true and important can't be written on Wikipedia, that is actually a problem. If something false can be written on Wikipedia because a truthy source has said it, that's a huge problem.
Wikipedia should also acknowledge that a source can be trustworthy in some areas and not in others, and that e.g. someone posting evidence of their own statements is more trustworthy than a third party saying what they said.
In short, it's not hard imagining better policies. It's maybe hard to imagine getting them implemented in the most socially gamed institution on the internet.
