How to Create a Learning Resource That Will Be Received Well and Used

Quizlet is an education startup, which hopefully for me will go public this year. But that's a rare case of something actually working out in the edtech space. I think people need to approach the problem of how do you create a learning resource that's going to be received well and used? You need to think as critically and intentionally about that as you would building an engineering project. And so if you're successful, your users leave but then they should be telling other people how they learned.
