Something I have taken interest in recently is Web Typography. Like graphic design, it is something I have very little experience with, but am pursuing in order to become a better Web designer. You may have noticed some changes to the typeface of this site in an effort to be more readable, artsy, and generally elitist.
A subject I DO know a great deal about on the other hand, is accessibility. So, when these two subject areas colided recently. I took an interest.
Accessible Web Typography is a resource that looks like it will prove to be very valuable. Perhaps you will find it to be as well.
