Well Hacker News is probably also at least 50% cold reading (I made that number up, but still). It's a constant repetition of what we want to hear. Similar to the Men's Health Magazines that tell us we can get a sixpack stomach within a week.

I mean it is only a matter of time until somebody (maybe a psychic, or a venture capitalists) figures out what we want to hear and feeds it to us. Of course the psychics also had to adapt to modern times.
