As most of you know, the whole community wiki for questions idea has been thought and re-thought. Polls and lists of also have. The one item per answer policy has been up for debate. Right now as an example of all of these things, we have What Are Good Reads about Writing.
Before we enter public beta, it might be good to clarify a policy about questions like these. Cooking.SE, which I participate in, has a pretty strict no community wiki unless the system kicks in and creates it policy. This is designed to discourage list of X questions or polls.
Do we on Writers want to have community wiki for polls? Do we want to encourage this for one item per answer questions? Or do we want to encourage questions like the one linked?
