I believe proofreading is very underrated. The way people write in e-mails, memos, contracts, and documents effects they way people are viewed. Everytime someone writes something it should be checked over and over for accuracy. The smallest mistake could jeopardize the entire paper and the competency of the person’s character. Using scrap paper or making a rough draft is useful in all types of writing. I know even when I write 1 line emails to my teachers I try and make sure there are no mistakes. When teachers grade your papers they could remember the sloppy e-mail you wrote them and it could effect the grade of your paper. The presentation on this topic suggest to go backwards but I think they are better ways to proofread. Going backwards may find spelling mistakes but it does not check the content of the paper. Reading aloud or having multiple viewpoints are the best ways to proofread. This link http://owl.english.purdue.edu/handouts/general/gl_edit.html explains the differences between proofreading and editing and explains when each technique is useful.
