Before the question Intuitive explanation of concentration of the measure for spheres has been marked as duplicate (correctly I believe), it has got an answer which might provide additional useful information. When viewing the question whose duplicate it is there is no way to know about it.
There seems to be some discussion on meta related to this in Closing as duplicate, but it seems that nothing definite has come out of it.
In fact also more generally there might be cases when there is something useful in answers to closed questions although I cannot think of any other specific examples.
Do you agree there is a problem here? If not, why? If yes, do you have a proposal for it? I cannot think of any satisfactory solution but I think something must be done about it.
Update: I now have an example of that different kind, - a question closed as off-topic (maybe rightly so) with a really beautiful answer: Are there any rational solutions to this octic equation? - a clear instance of the already widely discussed stone soup, though
