Hmm, I have upvoted your post, because I think it is a good idea to ask the question, but I am not completely convinced it is really a good idea.
The real added-value of Perl Monks is really the deep collective knowledge of the collective monks on Perl.
Of course, PM monks collectively have many other competencies. For example, I am sometimes able to answer questions about Unix or sh or bash or or awk or vi or some even more specialized issues (and I do when I can). But am I an expert on these? Not really, most of the time (as an example, I have forgotten almost everything I knew about Python and awk ever since I took up Perl about 12 or 13 years ago). Collectively, people on a Linux forum are more likely to give better answers. Others can respond to Windows questions. But my point is that, on a real Perl question, I think that Perl Monks is really unbeatable (at least on average). But if the question is really off-topics, I am not sure that we are any better than other more specialized forums.
