Tutorial: Using Sharp Fonts On A GNOME Desktop

"Font rendering is still a little bit awkward and one of the last weaknesses of Linux desktops. This tutorial shows how you can make GNOME and all GNOME applications (such as Evolution, the file browser Nautilus, etc.) use sharp fonts. In fact, we will use the Microsoft Windows standard font, Tahoma, as the standard font in GNOME, too, which will make the desktop look quite familiar if you are used to working with a Windows desktop."
