in reply to How do you find nodes that need your answer most?
I see your point, but on the other hand, it is quite normal to see some posts not getting (correct) answers.
Many questions not only requires Perl knowledge to answer them, but also specific knowledge in certain areas. Remember that Perl is just a language, which you use to resolve your problems in all kind of different areas. If nobody here has the answer to a particular question, that's nothing but normal.
Chances are that those questions will stay in the same situation even with red flags raised. I am not saying that it will not help in all cases, but personally I think it will rarely help.
