The Technical University of Vienna has a blogging service for its students.
it was done by http://www.knallgrau.at the company that also hosts the weblog that you are reading here.
according to the press release:
they plan to enable 15000 students und 2500 Scientific People to start blogging. The project should be accompanied by research initiatives. They are inspired by other universities that also allow blogging.
looks like a good idea to me to generate Semantic Web content.
