I asked a question, and a discussion started in the comments, "Why would you wanna do that", etc. After a while, I figured out the answer to the question, which I posted as an answer. However, that didn't quite solve the whole problem, since there was an aspect of it remaining unsolved. Neither the question nor the answer had any votes.
To avoid confusing people reading the discussion by radically modifying the question, I decided instead to ask a new question, and reference the old one. Did I do the right thing?
