I agree with you 95%, but will add that I think having a project, or a clearly defined goal, can help people stay focused and motivated. Shooting whatever sort of happenstance comes around is fun, but for someone like me that behavior creates a massive waste of film, and a very large pile of negatives that I never know what to do with. And I do see things of interest, all the time. Sometimes a little bit of organization is a good thing.
I don't see where projects enter into the equation one way or the other.
The whole style silliness has nothing to do with what you shoot but how you shoot.
And that should evolve over time.
I couldn't think of anything witty to say so I left this blank.
