It might help if you were only allowed to downvote/edit/close on topics where you have proved yourself. If have gained some reputation answering Java questions, maybe that does not make me qualified to decide if a C++ question is suitable for the site. A bit like the fact that reputation from SO does not carry to other StackExchange sites.
