To me if the post is that helpful and doesn’t carry information that could even confused the reader the more, for me a simple illustration of anything in the forum that I understood is quality.
So just as the title has already asked what is quality post apart from this little I have just explained above?
theymos wrote about quality posts.

To have them, you must write less but read more, learn more, think more and spend more time when composing your posts. Quality posts don't need to be too long, as the content, information it carries is most important factor for its quality.

If you make ten thousand posts in a week, your activity will be capped and you will still be a Newbie. If you make ten thousand useless posts over any period of time, you will gain zero merit and you will still be a Newbie. You can rank up only by making good posts consistently. It's quality over quantity.

When trying to write quality posts, a lot of people act as though they're writing a book report for school: putting facts that we already know into their own words. Nobody wants to read that, and you will not get merit for it. Moreover, the length of your post and the quality of your English are only minor factors. In trying to write a quality post worthy of merit, you should offer new ideas, personal experiences, or perspectives that other forum users will actually find new and interesting.
