I grew up putting two spaces after a period. A few years ago, after reading an article arguing for one space, I decided to try single spaces, as open-mindedly as possible. However, after a few days I ended up going back to the double space, since the single space just looked plain ugly to me. To me single spaces make all sentences look like run-on sentences, at least visually. On a different, though my side lost this religious debate, I have higher hopes for the eventual demise of all caps (which always look ugly to me, even in document or section titles.)
