Possibly the two most important things a writer must consider are audience and purpose.
Communication can t happen without an other and it is useless without a general or specific agenda.
For a writer, it just makes good sense to know who you are directing your work toward and what it is you want your work to accomplish. And it s equally important that your reader feels a part of your intended audience and that she understands what you want your work to say to her. The terms are symbiotic. While audience and purpose are the writer s main concerns, the way a paper s purpose is offered to the audience lies in the paper s thesis, the presentation, in writing, of the paper s main idea. The thesis is what connects audience with purpose and thus deserves much attention.
