Sharing my personal experience, not speaking for GitLab here:

One thing I did when I was excited about the Developer Evangelist role: I started writing a document in the open, collecting thoughts what I learned, what I want to do, and which ideas could help this drive forward. Markdown, Web IDE, Git commits. Don't check the commit times, they might be at 3am in the morning from an iPad :-)

It was too ambitious, and strategies changed. Still, it allowed me create a single source of truth and define a path forward, preparing for coffee chats and later interviews. I like to come back occasionally for ideas on new content :)
