I just came across a great resource when it comes to common typographic “sins” that are committed by both designers and writers.
The list is located on Ray Elder’s site (R+) and offers 34 common mistakes users make in typography. I admit that I’ve committed most of these sins at one time or another — some out of ignorance and others out of simple laziness.
