  <p>I don't want to continually change the wording of a problem</p>

<p>This is fine, so long as the question doesn't have answers, or if it has, say, one answer that can also be updated. But if there are 6 answers, all working against the assumptions in the original question, then that might be problematic.</p>

<p>This of course also depends how radically you are <em>changing</em> the question. Are you elaborating and adding more detail, or are you altering the basic premise of the question as you go?</p>

<p>Editing is <em>almost always a net good</em>, but if you have reason to believe your question is built on shifting sands, better to keep it in draft form for a while until you solidify it a bit more. Otherwise your edits will undermine the very people who are so generously contributing their time to formulate answers to your question ...</p>

<p>In short: it depends. </p>

<p>(and it's also possible to leave your question as-is and ask a followup question, too.)</p>
