I thought about this and realized that since having converted my reading habits almost entirely to blogs I have been retraining my consumption habits from passive to participatory. I now expect to be able to leave a comment at the end of an article, or email the author to ask a question. I expect media consumption to be participatory! What a strange expectation...
