I’m working to incorporate some more varied fonts into a new design without resorting to Flash or image replacement. I ran across this article at sitepoint. The stacks are a little dense. I’m personally going for a simpler route with fewer fonts, but it’s helpful to see another take on this. I will be picking up a copy of Vista so I can see what the new MS fonts look like. I haven’t seen Cambria or Calibri yet.
