Hi Nat G.,
What I was trying to say here is that some people (who do not use social media) feel that these abbreviated words like yolo, lol, and ttyl are illogical. They see these words as ruining the language. Many of these abbreviated words come from digital subcultures. When I refer to print rules (and I apologize for not making it clear), I am referring to organizational rules of laying print out i.e. white space, left to right, and how we place text into columns. In the last paragraph, I talk about one of the ways McLuhan lays out one of his pages and how I had to read it using a mirror.
Thank you for your input. I appreciate it.
