I agree that the distinctions between code and craft are pretty blurred. Also Seekers of Perl Wisdom and Q&A are similarly, er, similar.
Perhaps the Craft section should consist of shining examples of code which high level monks have selected from throughout the rest of the monastery and is not posted to directly? ie a sort of moderated 'hall of fame' for code.
Update: I've just noticed that the Guide to the Monastery gives a brief outline of each section.
