<p>I am not in favor of allowing more than one answer. This will encourage multiple reformulation and at the end we will have thousand of times the reformulation of the same answer. In a sence we should vote down (I don't do it) reformulation answer because a comment on the first answer to ameliorate the first answer will clarify things for the reader. I strongly believe that the temptation to reformulate should not be encouraged. </p>
