I don't know how else to express this. The font in "wall of text"-style questions is much harder to read than on SO. On SO, the font on posts is so much cleaner. Also, why is italics bold?
The font is also harder to read in other places on the site. I think you should change it to something easier on the eye.
font-family: Arial,Liberation Sans,DejaVu Sans,sans-serif;
. Movies is set tofont-family: 'Helvetica Neue',Arial,sans-serif;
. Probably you're seeing the fonts "the same" because you don't have Helvetica installed.
