Many books have been written based on blogs, but few actually receive my respect. Seventy-nine Short Essays on Design is the result of many writings by Michael Beirut at the outstanding blog Design Observer, with 272 pages discussing design with no pictures at all (only 79 different typefaces).
Michael made an interesting point on why to write (a book or a blog) :
“I’ve found that writing is a way to slow things down again, to question my own premises, to force myself to pay attention to things I might otherwise file away after the quick glance. (…)Â I discovered that putting the words on paper changes the claim those words make on your attention. Is it better? Is it worse? The answer may be different for every reader. As a designer, I am very grateful I’ve been given the opportunity to let you see for yourself.
