I have a confession to make: I love typography. And having just read Web Design is 95% Typography, I think I love it just a little bit more:
95% of the information on the web is written language. It is only logical to say that a web designer should get good training in the main discipline of shaping written information, in other words: Typography.
Macro-typography (overall text-structure) in contrast to micro typography (detailed aspects of type and spacing) covers many aspects of what we nowadays call “information design”.
Optimizing typography is optimizing readability, accessibility, usability(!), overall graphic balance.
