in reply to Are "PM Discussions" only to be technical?
As one of the authors cited in the nodes mentioned, I too feel compelled to reply. As it happened, I did initially post my node to PMD, which seemed to me to be the perfect spot for it (although if not I'm fine with that too). But once it was submitted I saw that I would not be able to edit the node.
Since I intend to update it periodically with new information, this was a bit of a disappointment. So I buzzed the CB and asked someone to approve it to Meditations. So if it's there now, it's only for reasons of editability. Even so, it's still my third choice. My second choice would have been the News section, but I'm 95% certain you can't edit root nodes there, either.
I wonder if these days it's still important to prevent PMDs for being edited a posteriori. For instance thepen's off-site archive records nodes more or less as they are posted, which means there is at least one way of identifying attempts at rewriting history. (Someone on the chatterbox suggested that PMDs aren't editable to prevent trollish nodes from being toned down).
