I don't write blog posts not because there is some bureaucracy stopping me (although I am sure there is bureaucracy), but because it's a poor use of my time. I have never in my career had a point where I felt I could sacrifice 1-2 workdays on a polished technical blog post. Even if all of one's planned tasks are on track (they are never on track - by design of the process, one inevitably takes on more tasks than time exists), there is always a years-deep backlog of papercut bugfixes, tech debt cleanups, and minor-ish feature requests, not to mention colleagues wanting some advice, rubber-duck design conversation, or in depth code reviews - doing any of which would be both more useful and more personally satisfying than writing a post.<p>I suspect people mainly write blogs only when required - either they are forced to promote themselves by their circumstances (they are between jobs or they are an independent consultant) or their boss asks them to (a tech blog makes for good PR for our project).
