What's photography?

While lots of writing about new technologies portrays their use as revolutionary and new, here's an example of a new use retroactively affecting an existing activity. In this case, photography.

The Guardian recently ran a piece on how documentary photograph-minded users of Google Street View troll it for unintentionally resonant images of street life. They then display these found images as documentary photography.

Whatever you think of photographers (can they just sit and search for images?), this is a startling new use of an existing (new) technology, and right up the alley of really new media.
