This is drawn from my experience today.
During my attempt to answer what I believed to be a fully-formed question about dragons, the question shifted rather dramatically away until, when I came back to the answer box to paste in the answer then format it for presentation, the entire look and feel, and the subject itself (to soldiers), of the question had been edited away. These were not trivial spelling or formatting, or "I forgot an additional clue" edits; it became radically different, such that I was convinced I pasted my answer to an irrelevant question.
In an effort to stave off the "disgruntled" opinion this may draw to me, I will say, "I am not disgruntled; my answer was completely OFF, and I realized it when reading the other solution(s)". I'm just asking "should a question remain "fully baked" once submitted, except for trivial, edits?
