Amusing and informative article by web designer, Paddy Donnelly that really hits the nail on the head. The article is a semi-rant at those designers who don’t bother to learn the differences between “too” and “to”, “it’s” and “its”, and “affect” and “effect” (These last two in particular I see people mixing up all the time). He points out that a designer who can’t spell or use correct grammar, is like a surgeon who can’t use a pencil. Of course, as designers, we’re not expected to write eloquent multi-thousand word essays all the time, but we do need to create and use copy, and basic spelling/grammar can really detract from what would otherwise be an excellent piece of design. Paddy helpfully includes a small guide at the bottom of his article, but this is only the tip of the iceberg. If you want to read further and improve your copy writing skills, I’d recommend getting William Zinsser’s excellent “On Writing Well”, and William Strunk Jr.’s classic “The Elements of Style”.
