Why is FiveFilters taking such interest in this particular anonymous Wikipedia editor? This doesn't look like simply an honest piece of investigative journalism, given how far FiveFilters seems to be going to promote this story (https://twitter.com/fivefilters/).
Why doesn't the article disclose the relationship between FiveFilters and Media Lens? The FiveFilters blog (http://blog.fivefilters.org/) mentions Media Lens three times (they've built tools for viewing Media Lens articles) and explicitly thanks Media Lens for making their content go viral.
There's a lot that doesn't quite add up.
