Last week I wandered into an online discussion group, where I was intrigued by the question,
“I just found out that I’m supposed to use one space after a period instead of two. After typing one way for so many years, it seems silly to change. Do you think it’s important to follow this rule?”
A little background: The double-space convention was a product of the old days of manual typesetting (I will spare you the boring details). And with old-style typewriters that made all characters the same width, a double-space was deemed necessary to distinguish the end of a sentence. But now that almost all of us compose on computers that can make those adjustments automatically, the single-space is sufficient. Confused? Me too.
