This is the Warwick stuff I was talking about:

This is the Warwick blogs page, where you can see the thousands of student blogs that exist.

This is an individual departmental section (Theatre studies) where the blogs seem to be quite focussed on academic subjects.

This publicity is how they got so many blogs going.

Warwick produced an in-house ‘BlogBuilder’ tool to do this. It is one of a range of web tools that they have produced and integrated with single sign-on.
