This is a quibble, but you might find it useful. The writer of this otherwise well-written article writes "i.e." where they should have written "e.g.". i.e. means "that is". e.g. means "for example". I have no idea why people keep getting this wrong.

My fav is et cetera ("and so on") where et is of course "and" and has its own symbol "&" (which, if you look closely, is clearly made of an "E" and a "t") and so you can abbreviate "etc." as "&c."
