You wrote this (now high-rated) wall of text just to further prove your point, didn't you?
This reminds me of that my highest rated so far answer at Stack Overflow was a big bullet pointed list.
I think the format itself (a list, where each item is at least a whole sentence) has a connotation of thoroughness and authority; and it reduces the TL;DR effect by presenting the content in small-but-not-trivial separable pieces.
Also, I see a “wall of text” as not having bullet points: being a series of long paragraphs without much structure visible without reading the text itself. The term is being misapplied to this comment in my opinion.
Currently, the comment for which I've received the most positive karma by a factor of four is a joke about institutionalized ass-rape. A secondhand joke, effectively a quote with no source cited. Furthermore, the comment had, at best, tangential relevance to the subject of discussion. If anyone were to provide a detailed explanation of why they voted as they did, I predict that I would be appreciative.
Based on this evidence, which priors need to be adjusted? Discuss.
