On Skeptics, the absence of hyperlinks in a post is a good indicator of a low quality question or answer:
- If the post is a question, then linking to examples of people actually arguing the claim you are skeptical of greatly improves the question by providing greater context and thus leads to better answers.
- If the post is an answer, the lack of hyperlinks correlates strongly with posts that are based in opinions.
If your title uses words that suggest your question will be subjective, the message "The question you're asking appears subjective and is likely to be closed." is displayed. I suggest a similar message is displayed if someone tries to submit a question that has no hyperlink.
Such a warning would catch at least some of these posts before they get posted.
