Clean and lean could be why you are so successful at moving your audience quickly through your product. It's the fact that you can help them find what they need with 2 taps/clicks or within the first twenty seconds. But it's possible that your emphasis is on surprise and delight. You would prefer that you keep them engaged for longer periods of time through a way of discovery. There is a huge difference between shopping for a product and looking to be entertained. I have experience doing both.
