Great art has to say something, and that something needs to be interesting.
It doesn't matter if it's a photo, a painting, a sculpture, a novel, a piece of music, a motion picture or any other work of art; it has to have something to say, or by definition, it's meaningless.
Some people get so caught up by whatever mechanics it takes to create a work of art that they all too often completely forget to to say anything. They worry too much about the technical end and completely overlook the far more important part of actually putting something interesting into their work.
In photography, too many people confuse buying cameras and playing with software with photography itself. Creating photographs has no more to do with cameras, lenses and software than drinking beer has to do with metal tanks and brewery equipment. What we use to create something has nothing to do with what that something eventually does or says.
