For years I try to explain to people, what OpenType really means and in which way it differs from TrueType and in which way it doesn’t. And I explain to people that it is safe to use a Windows TrueType font on the Mac in the year 2012 … (See my older article OpenType myths explained). And now with WOFF we have even a new format which raises new question …
So in addition to my articles I created this info graphic to explain the connection between the major outline font formats.
