Going back to Moses original statement that the only requirement in delivering your thoughts is that the receiving party comprehend it. That's a fair thought, but it's not quite that simple. If you see a child standing with their legs crossed, hands in front of them and squirming, it's safe to assume the child needs to go to the bathroom. We as adults have learned it's more appropriate to indicate that need via the use of words. That said, a sailor or truck driver will choose very different words than Southern Ladies at a social event to indicate they need to go to the bathroom.
Now let's switch over to learning, experience & exposure. I read through the posts in this thread and it seems one of the big issues is lack of learning or exposure to gain that experience and knowledge.
How many of you actually learned typography and layout in school along with everyone else in your class? I was born in the 60's so all my school work was handwritten. I learned to type on a manual typewriter in 7th grade and very little was discussed about formatting a letter other than you indent 5 spaces for the first word in the paragraph. Everything else was left-aligned. Skip to 11th grade and I had an awesome teacher who noticed a skill set I had. With only glancing at documents, I can spot format, typos & spacing errors without thoroughly reading the document. Because of my novelty skill, she showed me different layouts and some formatting rules - so that I actually had some exposure to them. No other students in my class learned about this kind of stuff.
Typography? I was about 19 when the coolest thing ever was when I learned you could take the daisy wheel out of a typewriter and switch from courier to orator! That was the extent of my typography training.
I feel blessed to have had as much exposure to so many different things in my life, yet there is always so much more to learn. I am a font-aholic. I have thousands of fonts organized on my computer. I design fonts that I need for my business or for personal projects. I have worked with all sorts of non-standard glyphs, but I can't tell you what a good majority of the glyph symbols mean or what their use is. What I know is all self-taught based on the exposure & resources I stumbled across over the years - because I have an interest in fonts & graphics and sought out more information not taught in my school classes.
Switching back to the ability to communicate ... While I would prefer to read a well-formatted document, I accept that the person writing it probably does not have that skill set. If I want to learn about the "Cladrastis kentukea" I will probably learn a lot more practical information from someone who works at a Kentucky tree farm and never used a computer, than if I talk to a person who formats & edits documents all day and studies modern dance at night in New York City. Team those two people up and they could produce a neatly formatted, valuable reference guide to the horticulture community.
I read recipes the same way I read science fiction. I get to the end and I think, "Well, that’s not going to happen."
