Two spaces after a period: Why you should never, ever do it.
I always type two spaces after a period. I’m used to it, and I’ve always thought that it was correct. Well, apparently it isn’t correct, confirmed by typographers and style guides alike. The linked article cites several reasons and arguments, but apparently it is primarily a matter of aesthetics. On that score I’m not sure that I see it, but I guess I’ll at least pay attention to my “type crimes” and consider switching, although it definitely won’t feel right (as evidenced by the fact that I couldn’t even switch while writing this post)…
