I'm spending some of this week planning a lecture that I'm giving to The College of St Mark and St John, AKA Marjon, for its PR degree course's PR in Practice module. I only just realised, having tried researching a fair bit, that Marjon was ranked by The Sunday Times, as the best Higher Education College in the UK! Will let you know how the undergrads receive blogs.
On other PR blogs, I notice that Jim Horton and Steve Rubel are blogging on the International Association of Online Communicators' blog. Really, really great stuff on there right now. Anyone who's wondering as a PR person what value blogs have should chech out the articles.
