My 'quick and dirty' attempt to show that minimalism should extend beyond just visuals - The same graphic as PNG which is about 60% smaller: http://imgur.com/mLdDj04 (admittedly I don't know the exact original font but the point stands).

Also, what are visually impaired people meant to do? A minimalist site should be much easier to keep screen-reader friendly. Pictures of text are not recommended.
