Side note; I would say that the discussion conventions of LessWrong discourage copious use of emphasis with things like bold, underline or all caps. The idea is that writers should strive to convince people with their words, and not with their formatting.
Formatting can be good for making distinctions or highlighting something. The overlap is, when the point that is being discussed, is whether two things are distinct/important or not.
