If your account is over 3 paragraphs, break it up into several posts. This isn't a rating ploy, people will read a thread with several posts... quicker than they will read a thread with only one post.
Since this is a subject that isn't discussed everyday, it takes a moment to process and understand the information. Posting in smaller blocks allows for quicker comprehension of the subject matter.
Remember this, although you are reading words it isn't the same on the eyes as reading a book printed on paper. You are reading light. It's harder on the eyes than reading printed material. Unconsciously an individual will skip over parts of a long post, because it is bothering the eye.... whereas a post that is broken up into smaller blocks gives the eyes a momentary chance to rest.
