Twitter, Facebook and the App Store will never, ever kill blogs.
From Say Everything:
Starting a blog continues to require no one else's permission. No App Store approval process sits athwart your path. And anyone with a Web browser can read your work. App Store offerings can tap into some capabilities of Apple's device hardware that a browser can't. But today any decent browser taps us into a teeming multitude of other people's minds. This choice isn't even a close call.
