Sometimes posts made by some of our people is confusing when reading the post, just want to emphasize on this because I know that long posts doesn't guarantee a quality post, but make your post to be understanding to the user, I know that necessity of people making a long post is because they needed a merit but that doesn't show a quality post, a quality post is a post that carries formative post not to be long without a good information or educate people of what they suppose know...people deviates from their area of concentration when they make a long post and sometimes their point will be pointless because of much mistakes ....its better for you to make a few lines of post that's meaningful than making 20 paragraphs with pointless narrative.
The problem is not the post's length but its content and organisation. Some posts should be long because they contain some information that needs to be explained. Others need to be brief because there is no need to elaborate on something that should be simply explained. Another very important factor in writing is how you organise your facts in sentences and paragraphs. This will enable readers to easily read and comprehend the writing. Generally, the length of the post doesn't determine the quality. A long or short thread could be a quality post, it all depends on the organisation and relevance.
