I'm a Software Engineer turned Marketer, and the gap between the two worlds is pretty big. I recently wrote about the #1 Marketing Mistake I made (which I think many other devs might fall into when thinking about marketing), which I think HN might like: https://www.nicksingh.com/posts/the-1-marketing-mistake-i-ma...
