CSS Naked Day
I'm taking part in CSS Naked Day. I think CSS Naked day is a good excuse to configure your browser so that the default rendering of things is aesthetically pleasing to you. At the very least, choose a font that doesn't look like ass when rendered on screen — I'm looking at you, Times New Roman — and possibly set the font size to something you can read comfortably.
For those few that it may interest, I currently have my browser's default font set to 13px Calibri, with monospaced stuff in 13px Consolas. I took a bit of a liking to Microsoft's new font families.
