I dwell in the world of aesthetics and visual design. I have terrible, god-awful handwriting, but my writing itself has been decent throughout my life. A teacher, a very good one at that, once told me, "You could write the world's best novel, but no one would care if they could barely read it"

Information, regardless of quality, is made pointless it reading it becomes more of a chore. The spacing, pacing and placement of words and writing are just as important as the actual content. When I write "disjoint"ly as you say, it is to separate thoughts. For instance, the first portion of Antoine's CS is meant to be dialogue between him and Malignitas, and the structure reflects that. Later on, there is a poem in a fairly simple, couplet rhyme scheme. 

However, after that, as you see, major paragraphs are wrote out in greater length, normally 4-6 sentences with 10-20 words. Admittedly, I would play around more with spacing, as I believe that single, double and no spacing add texture to paragraphs, but the current formatting only allows for the indention of entire lines of text, not a simple, actual indent. I would digress, however, and say that my single-space method of posting is really meant to make my paragraphs look clean and concise. Also, there are quite a few factors, such as paragraph pace, personal discussion, scene description, etc. that influence my paragraph structure and length.

Anyway, I'm not really harping on you. You're quite right in the fact it's personal preference. If I had a single request for anyone, it would be to indent every [b]other[/b] paragraph and single space between each one, but that is because I personally read it better that way in lieu of not having a proper indent function. I don't actually go as far as requesting that because how you write, as long as its quality is on par with the prerequisites, is up to you. I like to change up my sentence and paragraph structure on a whim, so being tethered down would bother me. In any case, single-spacing each paragraph is nice and helps flow. It's just a visual thing. I don't mean to make it sound like a lecture or something, but I'm sure I am.
