I've been a copyeditor and proofreader for three decades. For about 15 years I've also been doing technical writing, i.e., user documentation for various software and content management systems.
My interests are extremely diverse. I'm a hamster of learning, in that I find and chew off many bits of text and imagery on my travels and bring them back to my nest to digest. So I'm somewhat knowledgeable about many things, and not terribly knowlegeable about anything in particular. But I suppose I know the most about film and art.
