Florian Alt started his master thesis with us. He use the UsaProy (http://fnuked.de/usaproxy/) – a concept and software we (mainly Richard Atterer and Monika Wnuk) developed previously at LMU Munich – to create a new system that allows the annotation of web pages.
We think it is an interesting challenges to create a system that allows users to annotate any web page and make these annotations available to others.
With the concept we envision to bring Web 2.0 to any page and site in the WWW. Interactivity and community features are provided independently of the content provider and authors.
