OK, so I just got nailed on this trying to correct my boss's grammar. I told him that he should have two spaces after his periods and couldn’t believe he didn’t know that. Then, just to check myself I did a google search and came up with all sorts of resources saying that you should only put one space after a period because we aren’t limited to fixed length character sets anymore. How did I miss this? Is it really correct to put only one space after punctuation? Will I ever be able to undo years of double tapping the spacebar?
