Well I've perused a bunch of other business ideas to various stages :) So Edgar wasn't the only one. Before I launched Edgar I was teaching social media classes and taught a class that taught people how to do manually what Edgar does for you automatically.

(We've updated the class and you can still take it at https://edgar-university.teachable.com/p/social-brilliant)

People were paying for the class and actually implementing the strategy, so it seemed reasonable that they would pay for software to have it done for them. That guess turned out to be correct :)
