The first area I tend to think about when it comes to developer marketing is around advocates. A simple definition of an advocate is someone that speaks/writes in favor of some thing.
Creating advocates is a means of creating more of myself to go out and talk loudly and ideally effectively. However, they do take time to cultivate and it is a hard item to track. But by cultivating advocates I’m able to scale what would otherwise be a bottleneck of my own personal time.
