The 50 Best Websites of 2011

Some of the Web's best sites consist of variations on one simple idea. In the case of Dear Photograph, that idea is taking a snapshot — usually one featuring one or more people and dating from the film-photography era — and holding it up against the original setting so that past and present blend into a new work of art. The images contributed by the site's readers are wonderfully evocative. Looking at the family photos of strangers was never so transfixing.
