Looking at the tour, I realized (after reading a comment), that our Tour doesn't include best practices and requirements for how to answer a question that includes citations or good subjective/bad subjective information.
Because of that, new users may really get put off by seeing downvotes from those types of answers that don't have that criteria because they never learned that they needed to have it.
It seems like a good idea to include that information in the tour - which may reduce bad subjective or unsupported answers.
