An anonymous reader writes "Over at Slate, Farhad Manjoo struck a nerve earlier this year with a vitriolic article attacking anyone who would dare to put two spaces after a period, a post with thousands of comments (and counting) and dozens of online responses. (http://www.slate.com/articles/technology/technology/2011/01/space_invaders.html) He blames the two-space rule on the history of typewriters and ignorance of a consensus among typographers that supposedly goes far back in history. But the recent linked blog post cites numerous sources showing that Manjoo and typographers don't know their own history. It turns out that single-spacing is the aberrant practice, only introduced because technology made people lazier, publishers wanted to save money, and typesetters became dumber. The creators of many historical typefaces still in use today are apparently rolling over in their graves over the current standard. (Note: Slashdot ran an Ask Slashdot story on the topic of spacing last year: http://ask.slashdot.org/story/10/08/04/161232/sentence-spacing-1-space-or-2)"
