I accept an answer to my question. Years later, the question still stands but the answer is obsolete and there may be a more appropriate answer.
Should I unaccept it?
There are some small variations:
- If there are now two good answers to the exact same question, I think the right approach is to update the answer to clarify the subtleties and provide all answers in one place, in suitable context.
- If there are now two good questions, the right approach is probably to clarify the question and ask a new one.
- But the topic of this question: if the original answer is now obsolete, and has only historical value, but the original question is still relevant: is it correct to say so in a comment and accept a new more relevant answer or no answer?
This question deals with comment etiquette in such situations.
