For clear and entertaining literature, op-ed, humor or how-to articles? I believe in keeping things short, wherever possible. Wherever you might have some cantankerous or overly-technical material that needs to be made readable, or if you just need someone who can riff on nebulous, unformed seeds of thought? Some stack of research you need distilled into something more accessable than a formulaic abstract? That's kinda my thing, over here. You'll have to expect some vernacular. Dry reads are for kindling.
