The idea is to give developers a sense of growth without infringing on their time or requiring them to dig around the web for informative content in a million places.
As a software developer myself, i've often been really annoyed by how much i have to dig around to find good, concise content that is well structured and fluff free. I'd like to come away each week with informative content that makes me feel like ive learned something. So i'm gauging interest in a newsletter that would do just that!
