The advice section Do Your Job Better in the Chronicle of Higher Education includes regular writing advice columns from Rachel Toor, a writer and professor at Eastern Washington University. Although the columns are targeted towards academics and students, the advice often applies to the general writer. I often read the Chronicle's writing advice because it is usually relevant and of high quality. I think that must be because professor-types have been trained to be horrible writers (emphasis on the passive voice, incomprehensible language and style, etc.) and now professional writers must step in to reverse bad training.

In a recent column, "How do you learn to edit yourself?", Toor emphasizes the importance of the basics (like knowing the difference between further and farther and recognizing a comma splice when you see one) and recommends a few good style guides.
