I do not read all the responses here before answering a question. It is because, I think it is a waste of time. Moreover, when we actually go to the editor to answer the question, knowingly or unknowingly, we may say or repeat what has been said already. I do not want this to happen.
I want my answers to be unique and from my mind from what I have already learned on the question. This way, I am able to share my knowledge on the question asked to the extent possible which will also satisfy the person who asked the question. And who knows, if he liked my answer, he may give me a thanks too in the bargain.
