Flickr is a photo-sharing website where anyone can upload and tag photos, browse others’ photos, and add comments and annotations. Users can create photo sets and collections to manage content and participate in topical groups to cultivate a sense of community. Although Flickr is ostensibly for photos, the site might more aptly be described as a venue for sharing experiences and building relationships. The site provides the tools, but the value derives from the contributions of the user community — photos, comments, ratings, and organization — and the connections that the site facilitates between individuals. In this way, Flickr embodies what has come to be known as Web 2.0 technology.
