It is a nice option. On the forums that I have any sort of control over, I make sure that there is some light one, and dark one, and then some so-crazy-your-eyes-are-going-to-pop-out-of-your-head-from-the-bright-colors one as well.
Glad to see that you found yet another thing to make your life here more enjoyable! PLUS you probably just tipped someone else off to it so that they can switch as well.
