Some people perceive creative writers and technical writers as opposites.
The information isn't really your own-it usually belongs to an engineer or a developer. The technical writer's goal is not to entertain, but to educate or provide a service for a user who is in need. The majority of users don't read documentation or are not too happy about reading it due to its reputation for being dry and confusing. If something doesn't work, I can go back and change it. In tech writing, I am not in control of the product I'm writing about.
