A thought which often occurs to me when I see some font which I recognize on a poster, sign, or advertisement.

Many amateur (and amateurish) graphic designers seem to be quite fond of the old Macintosh system font, Chicago ... oblivious to the fact that it was designed for the old monochrome Mac 128k, and is really rather ugly as a display font. (Chicago has rather thick verticals and because it was intended to be able to be readable when dithered with the checkerboard pattern that represented an unavailable menu option in the early MacOS.)

Strangely enough, I've seen the Babylon 5 title font in lots of ads recently ...
