I'll trade typing [ ' ' ] for .  any day.  Easier to type, easier to 
read.  It's not just the character count, it's that you need to move 
your fingers off the home row (or, at the very least, a big stretch with 
your pinkie) to reach the brackets.  I suppose that depends on your 
particular keyboard layout and typing style/skill.
