Good list, though here comes my Hacker News-style pesky comment: Justified text on a screen is a feature that makes my eyes and brain hurt. Ragged text is much easier to read. Uneven and beautiful, like a plant whose details you rest your eyes upon as you observe, rather than a uniform concrete structure where vision is lost. (╯°□°)╯︵ ┻━┻ ┬─┬ノ( º _ ºノ)
Justified text is beautiful ... in narrow-ish columns with good hyphenation. But hyphenation sucks on the web, and without hyphenation you can't even do narrow columns even in the rare cases where it would make sense for the reader.
I don't plan to ever do something like this for any purpose, and I have never seen anybody do it either... But you can.
