I would be interested to hear more about your "selective algorithm" or what makes your content "the best"..
In other words: Why would I give you my email address?
I'm unsure how I could explain but I would love to try. My newsletter gets popular content that many developers found interesting. I then try to make sure that content is relevant and provides insights to the users. This project is still in its early stages but that's a simplified version of what I am trying to do.
Your ideas are intriguing to me and I wish to subscribe to your newsletter.
