The choice of a typeface, the care given to kerning and to readability—it all sends a powerful signal. When your business card is nothing but Arial on a piece of cardboard, you’ve just told people how they ought to think about you… precisely the opposite of what you were trying to do when you made the card in the first place.
I love typography. I don’t know if I’m any good at it, but I do think about it regularly, and I’m learning little by little.
At the very least, I promise you’ll never see Arial on this website.
