Having your SO question closed as off-topic or already answered isn’t believable to you? Just Google with site:StackOverflow.com and you won’t have to click through many results to find something closed.
Spending all of the time to log back into the site and try to find the closed question just to post it to HN to have more people try to nit-pick it again hardly sounds attractive.
> Of course, SO is a bad fit for helping beginners
The entire point of the story above was that it wasn’t a beginner question.
