I personally don't care too much one way or the other regarding spacing. I have never found it to be much of an issue as far as readability goes. What I do have a problem with is the constant bickering over which way is right. I have had teachers make me go back and change entire papers to fit their standard. Because I don't ever see a happy decision being made, I wish people would at least accept both ways of doing it. Nevertheless, I might end up sending this article to a few of my two-spacing friends.
I've always thought that two spacing was an issue in trying to make page length quotas. I've always done single spacing...just because. But to have a teacher make you redo a whole essay is just goofy.
I agree. My parents are two-spacers because "that's what they were taught and damnit, thats the way it should be!" So every time they read my single spaced papers they point it out to me. I feel like it's a pointless argument that does nothing but create quarrels.
