Jesse Schell mentioned the following article on Facebook, and I think it’s something worth passing on. I grew up told to put two spaces after a period. Then, I came to think of the space as a rhythm indicator for prose; two spaces equal two resting beats. I’ve long known one space had become the norm, but do we (including me) do it? No, I don’t, and my students in English 101 today admitted being taught to use two spaces. Only one student had been trained to use a single space. Thus, even when it comes to the “simple” period, the standards depend on circumstances. In taking a look at the article, we come to understand that typographical font with monospaced type would still require it. E-documents would not.
(Note how many spaces I used in my post.)
