Is there a way to change the typeface used in Safari's "Reader" mode? The typeface used in Safari's "Reader" mode (on both iOS and OS X) seems to be some form of Palatino, which, while certainly not the worst screen face, isn't the best either. This used to be a limitation in iBooks as well, until the addition of excellent screen faces like Charter and Athelas.

The easy way is to click on the "Aa" on the right side of address window once you are in reader mode already, and choose font and background colors :)
