We have a list of identified problems in Fedora or in the upstreams Fedora depends on. If you have the time and the skill, fixing them would help the Fedora text and font situation a lot.

The best way to try one's hand at font creation, and learn the (technical and organisational) ropes, is to contribute some time to a free/open font project, such as the ones listed on this page.
Most free/open font projects fail not because of author lack of artistic taste, but because they do not attract contributors or distributors. Free/open font dynamics are very different from proprietary font dynamics, and usually not taught in art school.
To start working on fonts just install the font-design group (available in Fedora 11 and later).
# yum groupinstall font-design
