I salute the habit, but I haven't had a commute of more than half an hour or so in many years, and unless you have a seat a broadsheet isn't the most comfortable reading anyway. I carry pocket-sized books on the subway for the most part, or easily foldable reads like the New Yorker.
Heh, this brought back a very nostalgic memory for me! When I first moved to San Francisco, passengers on Muni would fold their copies of the Chronicle in fourths, lengthwise, in order not to intrude on the other passengers. Haven't seen anyone do that for a long time. Sigh.
We were taught how to do that in high school. Which came a bit late for the students who had been commuting (and no doubt reading the Times) since seventh grade. It worked much better when the paper was wider; since it's shrunk (both in width and in page count), it feels terribly insubstantial when folded.
also when they shrunk it, they didn't make sure the columns lined up for the traditional style of folds, anymore. my high school commute was soooooo long that i had time to read the nyt and the wsj and still take a nap
