So, what you're saying is that TC has the same people working on rewrites and features? Doesn't it make more sense to give the busy work to interns and let the higher paid journalists do original content?
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.
When you cover a beat, a lot of times there are small stories that are worthy of a few paragraphs. But you often come across those stories while researching your beat and working on longer articles. So it often makes sense to divide up resources (the time of writers) based on topic rather than story length.
