Who do I raise the issue with?
CPAN is the main Perl site for anything not in core. Pretty much every Perl module you search on has search.cpan.org as one of the top three search results. eg MIME::Lite, Moose (second result), Plack (second result). In none of those does www.perl.org appear as a resource, with only perl.org appearing as a whitepaper on Plack.
