Open loops create an expectation for more. What could be more essential to making a reader hang on?
It’s critical in fact.
An open loop creates mystery. And to be solved it must be read all the way.

The web you create doesn’t necessarily have to be so wide, but it must be tightly woven in order to get the desired results.
Nothing tightens a web better than good ole open loops.
