I hope blogging won't disappear. It was really good for a while, when we still had blogrolls. Now it's all walled gardens, that make it even easier to share and comment. I kind of think it's time for the pendulum to swing back.
I doubt they will disappear. Blogs are perfect for anyone that wants to write online. Microblogging, or whatever, doesn't cut it. Twitter messages are too short. No, blogs won't be going anywhere. I believe they've become a permanent part of Web culture. Remember when Web sites had "guestbooks?" That functionality has essentially been replaced by comments on blogs.
If I had to guess, I think he's lamenting the relative death of blogs as indie publications of sorts (with novel designs and formats) and the migration of people to tools like Twitter and Facebook which are basically glorified, controlled forums.
I'm convinced the former type of blog has significantly gone away, but merely the marginal fringe of people who don't care too much about format seem to have swung away from them.
