I was walking around the lake today, multi-tasking by listening to a podcast: in this case an episode of the excellent "In our time" by Melvyn Bragg of BBC fame.
In this episode, Bragg was interviewing a group of British historians about the life and times of England during the 11th century. There were references to "Chroniclers", and the way they were described reminded me very much of todays Bloggers. The scale's not so grand of course, with respect to todays Bloggers, but you get the idea.
