There's a difference between the writing process and the written product. As I type, I have to double space between sentences -- it helps me set distinct ideas apart while reminding me that I need to find transitions between those ideas. The second space is a (psychological) gathering place -- a pause to reflect, look back, and then move forward.
I also like to use this little guy -- often when I'm supposed to use a semicolon, other times when I want to pause. It was good enough for Emily Dickinson, etc.
I had no idea I was so fired up about this.
EDIT: The woman says: "I double space after a full stop. I learned it when I learned typing in sixth grade."
