I just found the “Domestic Manners” font that I really like and feel is very good for extended text editing (terminal, coding, blogging, etc). Installing it for Fedora users is really easy:
sudo yum install dustin-domestic-manners-fonts fc-cache
You can set it in vim / your vimrc with:
set guifont=Domestic\ Manners\ 8
Also you can select it in the gnome-terminal font settings.
Attached are two screenshots of the font in action.
