I actually use some of the same interpretations you've made. When I'm trying to make intelligent discussion, I'll use proper capitalization/grammar/etc., but it still won't be proper written English because I'll still use slang and contractions and what not to make it more informal and more like how I actually talk. But sometimes, I will use lowercase when it's either very informal or I'm using fragmentary English in some way, or if I'm trying to portray the passive-aggressive sarcasm like you hate. A lot of my tone/humor IRL is based on my facial expressions and inflections, so to convert that to the internet I have to textually represent it in some way.

I find it interesting the way I have a slightly different voice whenever I'm writing a paper for a class than how I speak online. I mean, when I write a paper, it's still my voice; I be sure to not write anything that sounds weird spoken or that is too convoluted, because that's just not me. A lot of people write in some over-the-top formal voice and it just sounds stilted when you read it aloud. Yet on the internet, you basically are speaking through your text, and so it has to come across (to people you've never met) how you would say it if you were face to face with them.
