I was surprised by what seems to be standard used for body font-size .

The dev tools say it's rendering at 13px . By contrast on the browser (FF on W7) I was using 1em comes out at 16px . I wonder if some thought could be given to making the standard font size a little larger ?

As far as I know within Markdown there is now way of saying "make this bit of text smaller/bigger" so whatever is the default is what we're stuck with .

The size used does look OK on a mobile (FF and Chrome on Android).
