Well, the last case of a post ending (edit: or well, starting) in the wrong section is not really a newbie issue, because Nansh did it right the first time, and all following root nodes had to be moved...
If the section is renamed though, I think dropping the "Discussion" altogether might be better, like "About Perlmonks". And adding a link at the top of the Monastery Gates that directs the (logged in?) newbies to SoPW would be more helpful IMHO. Something like "Got a Perl question, or need help debugging your perl code?".
Edit: thanks ambrus for showing me how to post a link to the #post anchor of the node 479 :D
