The person who is the 200th best tennis player in the world does not worry about how the masses of crappy tennis players play or how they use their equipment. He tries only to get better.
Why should any of us worry or care about anything but being better?
I think part of it is covered in the question, "What constitutes 'getting better?'" Everybody has a different answer to this question, but in my eyes getting better constitutes getting recognition from my peers and just viewers in general. That may be a shallow view of improvement, but I cannot create photographs in a vacuum. I don't want to. Some people (like Vivian Maier) can take photos and be content with never showing them to anyone.
But when you want to share them and display them, then you're subject to the current trends and tastes of the public. That's why I find it relevant to study these trends and pay attention to them, not necessarily to copy them or "sell out" to them, but simply to keep a level head with the recognition that I can expect with my photos.
It might be a very cynical view, but it also keeps me from taking disingenuous photos that might - or might not - gain popularity, but mean little to me. At least I think that's a benefit...I don't know. It seems like creativity can be cultivated to an extent, but sometimes people have natural creative inclinations that align with what people want to see. And it makes me wonder if I lack that sort of inherent or learned creativity that allows me to capture the emotions and curiosity of viewers.
Art is so f***ing enigmatic and it pisses me off.
