Managing fonts on Mac OS X is hard. Much harder that it needs to be. By default there are three folders where fonts can reside. I am angry that Adobe decided to add additional font folders. These new font folders (one in /Library/Application Support/Adobe/Fonts and on in each application folder for InDesign and Illustrator) are only used by Adobe application. The system will never look into these folders to allow other application access to these fonts.
The only reason Adobe created these folders is greed.
