1. That was a pleasure to read. The limited width of the text columns was really a refreshing change. The link [3] in the page recommends a text width of 4 inches for easy readability. This is quite a useful thing to know, and hardly followed anywhere on the web. 2. Org mode in Emacs is a game changer for me. The pdf output via Latex is quite good. One thing I really used to hate was typing in beamer presentations by hand. Nowadays, I can make a org mode file super-quick and export via beamer to produce a basic PDF presentation.
