Where and how would I ask a question such as: "what do you consider to be the most profound question asked at stack.exchange.physics while you've been here?"
On the one hand I don't think it falls into the category of the sort of questions that should be asked since there is no right or wrong answer and is merely an opinion. Yet on the other hand, it seems to be similar to questions asked about book recommendations and could be tagged as wiki-community.
How would the moderators deal with it?
