This is what all you "designers" get for insisting on setting fonts and colors and whatnot. Now you have a Web where you have gotten everyone to force their tiny sans serif fonts and bright white backgrounds down my throat, but one Web site you like makes a change you don't like and suddenly you are up in arms. If people would leave the fonts and colors alone then everyone could set their browser how they liked and be happy.
I notice this guy has all kinds of fonts and colors explicitly defined in his blog's style sheet. He gets no sympathy from me.
