I know where you're coming from. You write a response, then the OP changes his/her node. You don't even realise it. But, the changes were drastic enough that they change your answer. And now your answer is out there, sticking out like a sore thumb among good answers (based on the new question).
This is a social problem, best met by a social solution, IMO.
