Why do journalists promote their stories as ‘my latest story on…’? How about ‘government agency X revealed today that Y and Z’? Or ‘on-going investigation reveals…’?
It’s the content, not the personality.
At the same time, if someone reports from experience, documented expertise, and obvious mental capacity, one may grant them qualified authority on specific topics.
But if someone is promoting their story just because they wrote it, that’s self-promotion, and I’ll usually move on.
