Respond the following questions in your post to the discussion board:
Who is your target audience?
What characteristics are unique to this group?
Why did you select this group?
What do you think is the most important message to share with your target audience?
What strategies will you use to convey your message?
I think it mostly depends on group/thing you are in. Assuming you are in a writing class, think of what books you like to read/write, and decide what audience that style/genre would most likely appeal to.
