Another thought about "public opinion."
It's not always worth anything. If Joe is writing a scholarly work on an obscure (but important) economist, the public's opinion will be close to useless. Many photographic pursuits are likewise specialized, academic, arcane, unusual, or narrowly focused in ways that would not capture public interest sufficiently wide to have meaning. Maybe a better example than writing would be film making. The public is interested in Marvel Superheroes, not "art films" made in Spain, or in a garage in Los Angeles. Exhibiting your work is still important, but the audience of interest might be the 1 unique visitor not so much the general public.
And from another angle, publican opinion can be downright dangerous to a photographer who is out on some narrow limb, let's say. A crushing public opinion could easily sew doubt where none is really due.
