That's no differentiation -- there's just writers. I can't speak to why that's the case -- maybe because they don't want to make anyone be the person who does nothing but crap work. I don't think anyone sets out planning to do a bunch of rewrites anyway. In my experience it just sneaks up on you "Oh, well we should probably cover this and I need a post, guess I'll just do this real quick." That's just my experience, but there's certainly no one at TC telling me to do rewrites. I guess there's also varying definitions of what constitutes a re-write -- I don't actually always depend on a press release or anyone's else's coverage for every news short news story.
