<p>I suggest that it is best kept closed. The one answer posted before it was closed  is a well-known example that deserves wide publicity, but I don't think there is enough focus to the notion of &quot;anecdote&quot; to stop the thread, were it re-opened, becoming an arbitrary ragbag of  case studies.</p>
