Irritatingly I have taken some noise recently on my original answer (prior to editing) here - My original answer was "Are you referring to "open secret"...".
This was jumped on almost immediately by a small number of people intent on pressuring me to conform to the "rule" that Answers are for answering and question may not be asked within them.
I completely agree with this principle- Using an answer to draw out more information or clarification from the OP is clearly wrong, I accept that and I uphold the principles of the SE family wherever I am. However, as I explained twice (one block of comments has since been withdrawn by me and their author), despite the fact my opening statement was interrogative, it was not actually a question it was merely a less formal way of offering my answer.
This seems to have got several people all excited and a few have offered admonitions and downvotes (seems like some people get more joy out of correcting others than offering helpful suggestions or answers, or maybe I am just suffering from selection bias) culminating with a polite request from a moderator not to frame answers as questions.
Now, having been somewhat annoyed by the entire approach to my answer I did check out, in detail, the documented rules for answering. I do believe that if I have broken rules then moderator intervention is justified and will be observed. However there do not seem to be any relevant guidelines for how to frame answers, certainly nothing that says you cannot ask a question in an answer, and nothing I can find justifying the interest from several people in trying to make me uncomfortable enough about my answer to conform to the stated "rule". It just isn't part of the "manifesto" of this site, yet has been metaphorically rubbed in my face and I have certainly seen the reaction deployed elsewhere here.
Why have I been put under so much pressure from community members and why was it felt that moderator intervention was justified? What community "rule" backs that up? I would be considerably less annoyed if I was genuinely asking a question designed to elicit information or even a response from the OP, but my answer style was merely less formal and more like how one person would speak to another in the real world. One person was so incensed that they edited my entire answer to make it the way they wanted to appear, together with reference (another common demand that appears nowhere in the "rules"), downvoted my answer and left a comment telling me they had done so because my answer did not actually answer the question.
I'm afraid that, given the lack of "real" rule, all the interventions seem somewhat petty and sanctimonious. In the end, following the moderator's response I did edit it as I have no desire to be a troublemaker. But I did not, and do not think that I needed to have done so and I feel slightly bullied.
