The new DK5 was obviously designed by people who type. Who don’t worry about design. How do I know? Some Kossacks have mentioned “too much white space” or “difficult”.
For more years than I care to mention, I did desktop publishing/word processing. As part of my skill set, I took classes in document design. It included fonts and their use.
Too many people think sans serif fonts (those without the little marks at the top and bottom of each letter) are cleaner, thus best to use for any and all documents. If you are not sure about the difference, here are a couple of pictures.
Sans Serif
Serif Font
Studies have shown that Serif fonts are easier to read because the serifs lead the eye to the next letter. Sans Serif are more difficult to read because each letter stops the eye from moving forward. So, in most cases, Serif should be used for body text (sentences, paragraphs, pages, etc.) while Sans Serif should be used as headings (either main document or to separate sections).
When I was on the Grand Jury, everyone wanted to use Sans Serif to write all the reports we needed to write. It took some convincing (especially as a woman, I wasn’t “qualified”) that I knew what I was talking about. Bringing in the books I had received during my training with the discussion highlighted finally convinced them to change the font.
Yes, this is a minor detail, but it would be so much easier to read diaries and comments if they were actually in fonts that could be read easily. Right now, it is a pain in the eyes to deal with this poorly designed “word processing”.
