I'd love a font weight option

Ideally an option to change the font; or just move to something other than helvetica; same issue on the site of course.

font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;

On a windows machine with all these fonts (thanks adobe font pack) it looks like this

A font-weight of 300 changes that to

Which is nicer and legible.
