web 2.0

Web 2.0, a catchphrase for the latest generation of Web sites where users contribute their own text, pictures and video content, is far less participatory than commonly assumed. A tiny 0.16 percent of visits to Google's top video-sharing site, YouTube, are by users seeking to upload video for others o watch, according to a study of online surfing data by Bill Tancer, an analyst with Web audience measurement firm Hitwise. Similarly, only two-tenths of one percent of visits to Flickr, a popular photo-editing site owned by Yahoo Inc., are to upload new photos, the Hitwise study found. Wikipedia, the anyone-can-edit online encyclopaedia, is the one exception cited in the Hitwise study: 4.6 percent of all visits to Wikipedia pages are to edit entries on the site.
