Yesterday we closed a question about the plugin directory, while last week we answered one. John P Bloch commented "If you have a problem with a WordPress.org plugin repository, I suggest you ask the people that run that website. They have plenty of outlets for such questions. This is simply the wrong place to ask that question." I think one could use this logic to say WordPress Answers is not needed, since we already have the WordPress.org forums.
Maybe we should take a step back and discuss whether we want these type of questions? I think they can be valuable, since they attract experts, and we need experts to keep this site alive.
