Reader feedback mechanism

I dunno -- I have a strong bias in favour of rate-this-article functionality on all articles in perpetuity :-)

Imagine all the many uses for that data. It would help us know which articles are poor, so editors could direct their energies towards them. Chapters could develop grant proposals for money to systematically increase quality in categories that rank particularly low. Editors who care about BLPs could identify the lowest-quality ones and dedicate sustained attention to fixing them. Professors could assign their classes to help clean up the 10 worst articles in their subject. If a particular language version was rated overall extremely high, other language versions could try to discern and emulate some of its practices. If a language version were rated particularly low, editors who speak that language could stage a quality improvement campaign helping it. Etc etc etc. The possibilities are endless :-)

I am afraid getting a number of negative ratings of an article would act pretty much demotivating for the principal editor of this article. Definitely, it would act in such a way on me, and it happened to me in the past (for instance, when a bunch of trolls recently coordinated an attack on my FA, even though I knew these are trolls).
