Good discussion and topic. I think it also depends on your audience and what they are looking for. I write various length articles from 3-4 min up to 11 to 12 min. My 8+ min articles tend to do better because they are in-depth investing and finance related. I don't get as many reads, but the readers spend more time on them. My 4 min articles never seem to get as much traction. But I'm sure others do well with short form.
