Is posting citations a compulsion even when the post contains self experiences?

Question

I have posted an answer for a post here, for which I got the below notification.

Now, what I don't understand here is why am I being asked to add citations to reliable resources, when there is no reference regarding compulsory citation given in the help section on any SO affiliated sites. There is only a mention regarding that if I am copying some material, only then I need to add the reference site/citation from where I copied it.

Whereas, in the above case, it's my own personal experiences which I have clearly mentioned.

I agree by this post that SE abides by the laws regarding any copyright issues and needs citations only when copying data/content from other sites.

But when I have not done any sort of copying data/text from other sites but my own personal experiences, then isn't this a wrong notification?

Answer 1

You are correct that citations are not required. But as written, your answer has three points; one (the last) is from personal experience and the first two appear to be opinion or common knowledge.

Additionally, your answer adds nothing that is not already posted in existing answers.

There is a post here that talks about some of the problems with short answers.

None of the answers on the question My dog lies down on its stomach with legs wide open are particularly good.

There is much room to write good answers to the questions, and your post could be the start of one. Adding references and expanding on the "why" would improve the answer considerably. You may also find while researching that there are things you had not expected.
