Abstract
Das World Wide Web (im Folgenden kurz als Web bezeichnet) verwandelt sich seit einigen Jahren von einem Medium der passiven Konsumenten von Inhalten hin zu einem Netz für aktive User, die Weblogs schreiben, in Foren diskutieren oder Podcasts veröffentlichen. Diese User der zweiten Generation gebrauchen das Web zum Gedankenaustausch und knüpfen als Knoten in virtuellen sozialen Netzwerken Beziehungen zu Gleichgesinnten, mit denen sie sich zu virtuellen Communities formieren. Folglich definiert sich die soziale Komponente des Web 2.0 über ein verändertes Verhalten seiner User. Web-2.0-Plattformen sind jedoch vielmehr sozio-technische Artefakte und basieren auf speziellen Anwendungen und Technologien. Erst die technologische Komponente des Web 2.0 ermöglicht, dass die sozialen Prozesse der User unterstützt werden. Der folgende Grundlagenbeitrag stellt wesentliche Anwendungen und Technologien des Web 2.0 vor.
