With some frequency I send feedback to Duolingo with a suggestion to correct a lesson. I do so when I believe to be right about an answer marked as wrong. Problem is, chances are I am still wrong but I just don't know it. This in turn, creates another problem: Since I don't hear back from Duolingo often, I have no way of knowing if that is the case or not.

So here is my suggestion: Why not create a public feedback section on the site where everybody can see these suggestions of corrections and rate them? This wouldn't affect the system at first but would allow others to agree/disagree with the suggestion and comment on it. Duolingo can then filter which are more likely candidates to correct properly the system.

What do you think?
