Comic Sans font has gained notoriety as the most hated font ever. It’s so dreadful and misused that there are many websites dedicated to banning and hating this font. No self-respecting web designer should ever use this font. It even appears in Weird Al Yankovic video “Tacky” (see around 1:15 minute mark):
It’s almost not funny because it’s true. The web is supposed to be this beautiful and lean, clean and standards-compliant creation and instead it’s often a mess of crutches and band-aids just to make sure everyone can see the website in browsers with broken or unsupported standards implementations.
