Different answer: You can write www pages happily for your entire life without ever using {position: absolute} -- or {position: anything-at-all} other than the default {position: static}.

The names aren't very well chosen, are they? If you didn't already know, you would have no idea what the difference is between "static" "absolute" and "fixed" -- and "relative" sounds as if it would be the default ("Just put it wherever it ends up") but it actually means something else.
