Maybe a stupid question, but... Does it really matter?

I mean when the node is first posted, it appears in the Newest Nodes pages, then, if approved, in the section pages and, if front paged, right on The Monastery Gates. In any case people are most likely going to see it. The only case where they might not is if they chose to visit Meditations and not Perl Monks Discussion or vice-versa.

Later on people might miss it if they run a Super Search on just one of those 2 sections.

Aren't those 2 cases rare enough that we should not bother, and thus leave the node where its author chose to post it, presumably after at least some thinking about it?

This seems to me like a case where the author should decide.
