This is by far the best thing we have read so far. Discussing the nuts and bolts (I have a dear obsession with nuts and bolts) of readability, and how to make things readable, and how to avoid making things unreadable was incredibly useful. Looking for line thickness, x-height, descender and ascender lengths and flourishes are things I never would have considered as increasing or decreasing readability.
Another interesting section of the text was on the shape of words. I had always just thought of using all caps as method of making things stand out more, but never considered how that actually made words less recognizable.
One thing I found particularly useful was Williams specifically highlighting points about when to do certain things (see When to increase Linespacing).
Thanks for the feedback; I’ve often wondered if this text was too dry for students in spite of it usefulness. I would recommend for future blogs, though, to refer to the specific texts you are analyzing so that readers outside of our class (remember that this is a public sphere technology) can better understand what you are discussing.
