Of the nodes tye cites, I believe that two were ones originally posted in PMD that I considered for a move to Meditations. The criteria I use to distinguish posts that belong in PMD from posts that belong in Meditations is simple:
in reply to Are "PM Discussions" only to be technical?
- Is the post substantially about either the mechanisms or the overt policies of Perlmonks?
If so, it belongs in PMD. Otherwise, it belongs in Meditations. At least that's my opinion; the Consideration mechanism invites other opinions to weigh in.
Discussion happens wherever the node happens to end up, so little is lost by enforcing the distinction.
