Well, I'm a photojournalism student at Temple university. I don't really shoot people for fun, but its enjoyable(I prefer landscapes) and I think you can covey an idea and be aesthetically pleasing at the same time. The most effective news photographs are art in their own right. Sure lots of news pictures are garbage, but some aren't. Really though, that applies for all photography. Its on the photographer to make a good image, not the genre.
I'd like to think that fine art and photojournalism can exist in harmony, I certainly don't plan to stop shooting fine art images when I turn pro. I think a good example of a photographer succeeding in both worlds is Lee Miller.
