When is a blog not a blog? This university’s vice chancellor has kept an online diary for three years; it’s prominent on the university homepage – VC Reflects. Yet it’s not a blog. There is no comment feature; no trackbacks.
On the other hand, it’s an exercise in public relations written for those outside the institution – and for its 3000 employees. The VC is addressing our student society later this evening.

An interesting question. I would say it’s a diary. As you point out it has no feature for interaction within the site and whilst it may generate discussion by the people who read it they can’t have their say within the web address and so it can’t be classed as a blog. Maybe the VC could be encouraged to ‘come over to the dark side’ and start blogging!
