The very first suggestion given to you was I think there should be a new Section on PerlMonks for Jobs/Modules/Quizzes/Perl6/Newbies/OffTopic/etc.. Did you not read it? It is full of examples of what "a 'Related Topics' section could be used for" and subsequently full of reasons why we don't need it. But if you want it then go write and implement it yourself instead of asking others to do your work for you.

Are you really suggesting somebody go implement their own perlmonks as a way to improve perlmonks?

Creating a new sections is something that needs no writing/implementation, its already implemented, its as trivial as creating a new question or answering a new question, click the mouse a few times, type a little (title, nodetype, groups), and you're done

Given you know so little about how perlmonks works, I'm pretty sure you don't know what we need
