I'm really interested in starting off my career as a Developer Evangelist. However, I'm not really sure how to grow it after? Will I be seen as "less of a programmer". Any Evangelists want to share their experience and growth?
Let me say this: I went to a meetup several months ago for an Angular event. The speaker was horribly unimpressive; quite literally copy and pasted code from the Angular Demo site in-front of us for the "demo", and couldn't answer in-depth questions. No one liked this "evangelist".
In short; have a conviction for what your evangelizing, and dig deep into it.
