I am prepared to bet a beer that while users have left for the bad quality of some questions, immensely more have come and remained for the good quality of our answers. My question is, precisely, how to weigh those two things. I posit that it is obvious that we do not have to 'weigh' or 'bal...

I wish I had a better portfolio of such examples. However, I was not able to find many of them.

In the future I'll use repost tag when discussing something like this in chat, so most likely such question could be found by searching in crude for the words repost or re-post.

This approach was also discussed here in chat:

Good answers on poor questions

So here are some examples of questions which I reposted, since the original was closed or deleted:

System of equations with radicals: $2\sqrt[4]{\frac{x^4}{3}+4}=1+\sqrt{\frac{3}{2}y^2}$ and $2\sqrt[4]{\frac{y^4}{3}+4} = 1+\sqrt{\frac{3}{2}x^2}$

Given distances (shortest paths) between four cities, how to show that they cannot be in the same plane? - it was also mentioned in crude: chat.stackexchange.com/transcript/2165/2016/6/8

Example of a topological space which is neither sequential nor $T_0$ - there is also a meta discussion linked in the comments.

How to show $\sum_{n=1}^{\infty}\frac{H_{n+1}}{n(n+1)}=2$? - see also discussion in crude chat.stackexchange.com/transcript/2165?m=43333261#43333261 and chat.stackexchange.com/transcript/2165?m=43333111#43333111

That's about all I can think of from my posts.

Asaf Karagila mentioned his question in a comment in some discussion on meta: Subset of a finite set is finite

Maybe such examples can be useful if there is wider discussion about this on meta.

Of course, reposting is different from improving posts by other users.

I kind of promised to find examples of that some time ago. Maybe I'll get around to it - but that list won't be impressive either.

I would be glad to know a partial list (at least of ten posts) which has been undeleted or reopened by the CRUDE users. No need to respond to me here (if at all) I also visit the CRUDE room sometimes and so you can respond there also (if at all). — user 170039 42 mins ago

If needed, I can try to compile some list of reopening initiated by discussions in this room where I participated. Most likely it won't be too impressive, since the stuff which I initiate most often are duplicates and merging.

I wish I had longer list of examples, but at least the ones I was able to remember can be found here: https://chat.stackexchange.com/transcript/19138/2018/4/5
