It's hard to tell if anyone's interested in reading a serialized story. But it's interesting to put in a cliffhanger each week. That was popular in old comic strips. They'd write a weekend story different from the daily strip. So people follow one story day to day, and a separate story on weekends. If you read them, you think "I'll read two more." Then you're like "I gotta find out!" And you read 500 more.
