One other problem is, magazines end. They have X articles, of which you find Y interesting enough to read, and then that's that. You read it. It's done. You go do something else.

Digital feeds never end. There's always something new, always something interesting. There's always something. You can keep staring at the screen endlessly. And if one app doesn't give new stuff anymore, there's 10 other apps within a tap away to give you more.
