This question already has an answer here:
I recently searched for an answer to a programming question with Google. After the search did not turn up anything, I went to Stack Overflow chat and asked there, because it was more a question about which solution to a problem I had was best (that means I had a solution already, but wasn't sure if it was best).
After some discussion some alternate solutions came up that I liked better. I had the idea that it might be a good question / answer pair since that way it would be documented for future searching.
So, would it be OK to create a question / answer pair on SO just for reference? Or is it better to just forget about it? What is the SO policy? Does that belong more on Programmers?
