Interesting post comparing slide design with the kind of typogaphy espoused in Robert Bringhurst's Elements of Typographic Style (one of my favourite books). Paraphrasing Bringhurst and replacing “typography” with “slide design” they come up with:
Slide design exists to honor content… In a world rife with unsolicited messages, a slide must often draw attention to itself before its message will be understood. Yet in order to be understood, it must relinquish the attention it has drawn. Slides with anything to say therefore aspire to a kind of statuesque transparency.
“Statuesque transparency”—I like that. The opposite of what Tufte calls poshlust (a Russian word meaning, apparently, “pretentious banality”). Ironically, often the best way to achieve this in a slide will be to get the typography right.
Elegant, subtle, type is often what sets apart professional design from amateur design. Even if we can't all be professional designers or typographers Garr Reynolds argues persuasively that we should take the time to learn a bit more about type. I agree wholeheartedly.
