After checking out Wattpad's info, my initial reaction to this new Amazon initiative was reinforced. Wattpad says "write your stories
in your own language", and that again made me think of the webtoons and serial novels so very popular in East Asia. The ubiquity of online serial novels can be seen from the number of times the protagonist in C-Dramas has this very occupation. So I would say that not only is the demographic Kindle's aiming at one with a lower average number of solar orbits than the MR crowd, it's also more likely
inside the circle, not just outside.
