Your post is quality but lacks one quality. One which I've scanned to see on the list and didn't find it. Maybe, it's there, if not there, I'll add that a quality post is a post with references to the source. And it adds more quality to the first point on your list. References on a particular answer to a question facilitates a better comprehension to the reader by encouraging them to further research about the subject.
No I don't agree that when you reference your post by putting the link or source for for it means you have make a good post, this is not really. Some post are just copied from the internet not original and it is boring and too much to read because the writer is looking for merit and thinking size of what they write will get them merit. IMO
Making source of your post is to avoid the offence of plagiarism and not because the post is fantastic
