Blogging as essay format

"For in Calormen, story-telling (whether the stories are true or made up) is a thing you're taught, just as English boys and girls are taught essay-writing. The difference is that people want to hear the stories, whereas I never heard of anyone who wanted to read the essays." The Horse and His Boy, C.S. Lewis

I wonder what he'd have thought of blogging. He wrote a pretty fair number of essays himself, many still eagerly read.
