I am against opinionated answers, unless an answer has some basis in formal theory (books, articles on HBR, etc...). Or there is a case study that has been presented in a public forum (conference, meetup) regarding a method that works - an opinion is not a good answer and should be downvoted and preferably removed.
At the same time, I believe that questions must not be voted to be closed because someone has an opinion that all answers will be opinionated. That is just killing a source of great knowledge without even allowing people to try and answer.
There are plenty of questions that ask very basic things, and in other context would be assumed to bring only opinionated answers. For example, "How do I persuade my boss to do X?". In the DevOps StackExchange, there ARE answers that come from formal theory (books, articles, etc...) and based on case studies of companies who are talking about their DevOps journey/transformation. These questions should be left open IMHO so that knowledgable people can collect and contribute the knowledge, turning this website into a very valuable resource for companies wishing to undergo a journey into DevOps.
To quote my comment on https://area51.meta.stackexchange.com/questions/26466/devops-site-description-too-narrow
There a ton of definitive knowledge that spans thousands of books and more than a hundred years of human endeavor. That knowledge has been battle tested in the field in many other industries, and also in IT. Just because most people have not read the books, and are not aware of this knowledge, does not mean the every answer to such questions is going to be an "opinion".
The above is also currently described at https://devops.stackexchange.com/help/dont-ask
Some subjective questions are allowed, but “subjective” does not mean “anything goes”. All subjective questions are expected to be constructive. What does that mean? Constructive subjective questions:
- inspire answers that explain “why” and “how”
- tend to have long, not short, answers
- have a constructive, fair, and impartial tone
- invite sharing experiences over opinions
- insist that opinion be backed up with facts and references
- are more than just mindless social fun
