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.

Citizen journalism refers to a wide range of activities in which everyday people contribute information or commentary about news events. With the birth of digital technologies, people now have unprecedented access to the tools of production and dissemination. Citizen journalism epitomizes the belief that the experiences of people personally involved with an issue present a different -- and often more complete -- picture of events than can be derived from the perspective of an outsider. Citizen journalism encompasses content ranging from user-submitted reviews on a Web site about movies to wiki-based news. It forces contributors to think objectively, asking probing questions and working to understand the context -- the kinds of activities that lead to deeper learning.

Cyberinfrastructure is not a new technology, per se, or merely a better, faster Internet. While cyberinfrastructure brings together high-performance computing, remote sensors, large data sets, middleware, and sophisticated applications (modeling, simulation, visualization), it also involves people as participants in the generation of knowledge, giving them the opportunity to share expertise, tools, and facilities. Cyberinfrastructure merges technology, data, and human resources into a seamless whole.

The "7 Things You Should Know About..." series from the EDUCAUSE Learning Initiative (ELI) provides concise information on emerging learning technologies. Each brief focuses on a single technology and describes what it is, where it is going, and why it matters to teaching and learning. Use these briefs for a no-jargon, quick overview of a topic and share them with time-pressed colleagues.
