<p>There are times when I answer here -- but, upon further reflection, it is clear that I'm not the best person to answer the question (because of lack of expertise or just confusion about the question). So I simply delete the answer. However, sometimes I feel this could be confusing to the person asking the question, as all of the commentary that goes with it also gets swept away.</p>
<p>Another issue is you can't leave a comment after which explains the reason for deletion.</p>
<p>Is there a best practice in this situation?</p>
