The two seem like an unlikely pair- the file sharing site that first introduced the world to free music, what does it have to do with writing? No matter how much people harangue the site, it is transforming the way people view writing and it all has to do with how we perceive writing as a society and how we receive writing. This also effects the ever so ubiquitous plagiarism cases that plagues universities and school and puts faculty in awkward or punisher position. If writing teachers employ the use of Napster for students to post and share documents (for reference and learning, not use) there is the ethics that must be employed to make sure it does not turn into plagiarism central. The Fair Use policy that DeVoss and Porter talk about seems like a really good approach to fend off plagiarism. The approach is based on teachers giving academic support to students to encourage them to write their won work. Extra supervision during the writing process will allow students to collaborate with their teachers and get feedback on their work early on in the revision process. I know some teachers I have had were totally supportive of asking questions about papers and working with you to make them well. On the other hand, there are some professors that are less accessible and harder to get in touch with. Fair Use also acknowledges that writing is intrinsically collaborative, nothing is ever new, and as authors we borrow and credit other writers into our work. Students just need to learn how to do this in a correct way that does not borrow without attribution. Plagiarism is too much a police catches the robber policy. Some teachers I had were just waiting for students to plagiarize, assigning really difficult literary analysis research papers and collecting our disks and using soft wear to detect any plagiarism. Teachers and students must work together to know expectations of their work and how they assemble it, or students may never know.
The more our society treats works as something that can shared and used to learn with, the less people may want to have strict copyright and authorship rules. Thus, people will respect the authors more and be aware that they do need to cite them or not illegally distribute these works. As soon as individuals stop acting like children in a kindergarten (MINE! MINE! MINE!) then perhaps sharing will become culturally more accepted.
