I am creating this post to gather in one place all the topics that are not clearly on-topic. (This is not the same as topics that are clearly not on-topic.) Please post as answers such topics, then users can upvote or downvote these answers, with upvotes meaning they think the topic is on-topic and downvotes meaning they think the topic is not on-topic.
