I somewhat agree. I wrote this from the standpoint of someone who's released a number of apps, some which have done well, and some which have not. There's always the frustration that I spent all this time on this thing that I thought was awesome, but that no one cared about actually using. It's targeted at people who have built those apps, know that pain and just want to make something that people will actually buy this time.
I have definitely written a number of apps that were super awesome and pushed the envelope, but they didn't actually sell, because they were before the market was ready, or in the wrong market, etc.
