I don't know, most StackOverflow answers I run into are "closed as duplicate of <not my question>" or "closed as duplicate of <how would I have solved my problem 8 years ago with only the tools available then>"
Slightly open-ended doesn't seem to be a problem for me on SO. Where I've really had a problem is the admins not reading the question properly then closing it as already answered elsewhere. I find that screeching like a banshee gets it apologetically reopened. Bit frustrating but a flawed SO is better than no SO at all.
