This question was adopted/stolen from the RPG Stack Exchange's Meta.
I asked a question about literature that was closed. Someone recommended that I try posting the question on another website. What are some good recommendations for other websites that would be a good fit for questions that would be closed here? In addition, are there any off-line communities (e.g. book clubs?) that would be a good place to discuss questions that would be closed here?
When answering this question, please post one website per answer. That way people can vote on which suggestions they feel are useful.
