Following up on a recent post, there are more people looking at pros and cons of reading difficulty. The question is being asked about E-readers now – do those wonderfully easy to read screens actually result in us retaining less information? More of those dots are connected in this article, though it seems like the studies to test the question remain to be done.
While not entirely the same thing, I also am being tempted by a new book, Typography for Lawyers, wherein research on the persuasive and emotional impact of various fonts is discussed and recommendations for fonts, layout, formatting, etc. are made for a specifically legal audience. (I found the book via this review which also recommends it.)
And of course there was the recent recent ranting over at Slate about people who put two spaces after a period.
