I've never understood why people code on dark backgrounds with such thick, fuzzy fonts. I find it extremely hard to read and have instead grown used to coding on an off-white background. Fonts are just rendered much thinner in a dark color on a light background (or at least, they seem to be). There's more space between legs and inside the o's in the letters. I find it much easier to read.

I've spent many hours trying to figure out how to convince Vim and/or OS X to lighten up on their font rendering. For some reason the only place I've been able to pull this off is Drracket which I just use for a class, and which has an option to do it. I've never been able to pull it off in my standard coding environment. I can't understand why that option isn't available anywhere else, or on an operating system level.

This is Monaco 12pt in Drracket and Vim, with that Drracket font smoothing option at the bottom: http://i.imgur.com/Va0ZN.png

Is there a good reason there's such little control over font rendering, at least on Mac?
