Jason Fried deserves to have a billion dollar business with Hey. He is super smart and he has brilliant design ideas thinking from First Principles
But the vast majority of people will never know about it because Hey is hard to switch to.
With Spike email if you have any of the popular email systems you can try in 30 seconds without giving up your existing email client.
But with Hey you have to switch to Basecamps servers. So everyone I know who knows about Hey has been too reluctant to try it.
So Hey will end up like Bitkeeper or Betamax. Shame -
