It certainly is a good idea, but I wonder inhowfar the goals differ at all from those of Seekers of Perl Wisdom and/or Meditations? Both of these sections offer a place for this kind of question - SoPW on a different level than Med. My own snippets and idioms I sought advice about went into aforementioned sections. It seemed appropriate to put them there, and they fit right in indeed.
I think the issue is less one of offering a place for such scrutiny, but rather one of encouraging people to seek advice about their code. There is often a lack of awareness with beginners that makes them unlikely to suspect any problems in their code that might make them seek advice; raising awareness is really what we have to achieve.
The questions will follow, and we already have the areas to accomodate them.
