As one of the principals in a CB discusion that erupted over "Religion in the Monastery." being moved, I feel compelled to post a reply...   ahem...   Well said, tye.

I had developed the opinion that Perl Monks Discussion was for discussing framework facets of PM as a site (voting, experience, markup, etc.).   Barring any supporting posts in this thread that are as sensible, well-researched, and eloquent as "Are "PM Discussions" only to be technical?", my thinking will doubtless be swayed to agreement with brer tye.

Update/Clarification: my original thinking was the opposite of what tye says above.   In light of his compelling and clear arguments, I now agree with him that posts primarily about social aspects of the Monastery would generally be best posted to Perl Monks Discussion, along with posts on mechanical facets of this site.

Two benefits come to mind for as-consistant-as-is-reasonably-practical placement of nodes within sections:
  A - facilitates more effective topical searches in the future
  II - provides a more consistant and grok-able user interface for monks both new and old.
Clear & public recommendations/guidelines for best-practice node placement would seem to be a big part of this.
