There have been many instances where i have had to adjust my writing style to suit an audience. The most recent instance I can think of would have to be the application and scholarship process before college. Many of the scholarships are looking for different types of writing and other special characteristics in order to be one the recipients. In each other the different scholarships, I had to adjust and tweak the ways i approached different topics in order to even be considered for the scholarship. If I would have approached each one the exact same way or wrote it exactly the same, I would have automatically been disregarded from any consideration. Whatever you are writing for I believe it is very essential and necessary to adjust the way you write to an audience.
