I agree, this post really does not have any concrete lessons. It has a few nice cliches but nothing that is truly a lesson you can use on your own projects. But that's probably also because it doesn't really get into any details of how they truly made a compelling product. Those details are glossed over as "talents" and "trial and error." That's where the interesting details are.
