Apparently, that is all wrong:
Yet when he sits down to type, Julian Assange reverts to an antiquated habit that would not have been out of place in the secretarial pools of the 1950s: He uses two spaces after every period. Which—for the record—is totally, completely, utterly, and inarguably wrong.
This is shocking news to me. No one has ever told me this, and no teacher (or anyone else) has corrected me on this. I always use two spaces after a period. In fact, that last sentence and every other sentence in every blog post on here? Two spaces after the period. Every brief, motion, e-mail, letter, and everything else that I have typed since I learned how to type has included two spaces after each period. (I believe maybe once or twice in an effort to fit into page limitations I may have used one space, but it felt wrong and dirty.)
I'm not sure this is something I can change at this point in my life. I'm simply too much in the habit of two spaces after a period. Also, I'm not sure it's something I want to expend the effort to change. Now, I type without even thinking about it. If I try to only use one space after a period, I will have to think about it. One space. That's it. Stop right there! Ugh. It's very disconcerting to find out that you've been doing something completely, utterly, and inarguably wrong for 23 years.
