While the article is targeted at PC developers writing games, I think there's a lot that can be taken away for Mac developers as well. Just try and imagine how what he's saying could be applied to what a Mac developer is doing.
My favorite paragraph:
One of the jokes I've seen in the desktop enhancement market is how "ugly" WindowBlinds skins are (though there are plenty of awesome ones too). But the thing is, the people who buy WindowBlinds tend to like a different style of skin than the people who would never buy it in the first place. Natural selection, so to speak, over many years has created a number of styles that seem to be unique to people who actually buy WindowBlinds. That's the problem with piracy. What gets made targets people who buy it, not the people who would never buy it in the first place. When someone complains about "fat borders" on some popular WindowBlinds skin my question is always "Would you buy WindowBlinds even if there was a perfect skin for you?" and the answer is inevitably "Probably not". That's how it works in every market -- the people who buy stuff call the shots. Only in the PC game market are the people who pirate stuff still getting the overwhelming percentage of development resources and editorial support.
