Hi,
I need your feedback about a scenario that could be useful especially for articles with lots of people prevented from editing it because auf conflicts of interests. Assuming that employees from a company would have a look at all the articles about them, their products, their projects, biographical articles about their board members and so on, would it make sense to put all these collected comments to a single site accessible to Wikipedians?
En.wp has sites such as http://en.wikipedia.org/wiki/Wikipedia:External_peer_review where (mostly journalistic / scientific) statements about wikipedia articles are collected. When Nature released the list of feedback on 42 articles, the result was amazing. Currently, External peer review has nothing to do with COI, of course.
