From a personal point of view, even I won’t ally with Series. I’m not even sure if I’ll ever create one; at least not soon enough. But if we take a large number of Medium users into account, I’m afraid our kind of audience would be in minority.
Story and Series are like two kinds of movements in a turn-based game which don’t compliment each other; they might as well work against each other to some extent. It somehow doesn’t feel right to put them together.
