Joe, how do I find your flickr stream? You don't mention it on your blog.
I do some shooting reminiscent (to me) of the photography of Andre Kertesz, Robert Frank, et al, which I guess loosely defines "street photography" for me. But I don't call myself a street photographer.
My interest in making photographs is to express what I see, what I'm feeling, the life and things I see around me in their myriad interactions, and share those perceptions with others. Street photography is a subset of that which focuses on the interactions—or juxtapositions—of people and things in the shared public space.
Street photography should, in a sense, document people, their society, and culture as filtered by a camera's lens and photographer's eye. That's how I think of it.
