In the Bay Area the greatest demand is for technical writers, particularly those with programming expertise. This depends mainly on the courses that you decide to take and on the projects that you develop for your portfolio. The specialization that you develop through your classes and assignment choices can help you to position yourself in the industry or area of writing that you're most interested in. However, it is sometimes harder for new writers to support themselves solely through independent writing. Therefore, some beginning writers work full-time initially to prepare themselves to bid successfully for contract work.
Salaries vary greatly, especially since many writers work as freelancers or contract hires.
Also, more high-tech jobs tend to pay higher. Roles for interactive scriptwriters, interface designers, producers, and content editors often draw on more traditional technical and professional writing skills. Multimedia involves aspects both of promotions and publishing. Most multimedia products require supporting printed materials as well. Technical and professional writers must be well-organized, clear thinkers with adaptable styles.
