How do I judge a quality post?
I would rather not keep mute as you are asking for my own view of a quality post. Quality is defined by the level of excellence projected.
Quality posts are not necessarily determined by length as a post can be lengthy but not qualitative. This does not rule out the fact that if a post must be qualitative, it has to be full.
I believe a qualitative post must have a lot of images and illustrations to better buttress the writer's points.
To me, I believe a post is qualitative if it answers all or most of the possible questions readers might have in mind under the chosen topic.
