Having sat down and squint-slogged my way through the "Stop Stealing Sheep & find out how type works" book, I am here to inform you that it is not good, often patronizing, frequently and profoundly wrong when it comes to technology, smugly ignores its own advice about basically everything, makes only the barest nod to the idea that legibility matters and doesn't admit the idea of accessibility at all.
My advice is: just steal the sheep.
