As type designers who do you design for?
Who is your target audience?
Is it the professional user (aka Graphic Designer)?
Are architects, accountants, plumbers at all in the picture (aka the lay man)?
Do you design with a particular end use in mind (ie, a nightclub flyer, annual report, web)?
Or do you design to fit a particular foundry you desire to be represented by?
These and many other questions about type designers' audience plague my mind.
(Let's skip commisioned typefaces, as those serve very specific needs and come with many requirements)
