The idea is based on Pat Walls StarterStory which is now making $12k per month, mostly through a paid membership.
I like businesses like this because they are very simple and focused.
Marketing Idea: This is a good example of the benefits of launching on ProductHunt and Hackernews even with a basic interview website. You don’t need to have a unique app or business model to get attention if you have a network to support your launch. I’ll be launching on those sites in a little while as well.
