Marco on consumer mindsets:
"Anyone who tries a paywall on a website (at any price), or tries to charge $30 for a mobile app, is going to lose most potential readers or customers. (This might not correspond to lower profits.) They’re breaking the market’s price expectations by pricing above the boundary for what’s usually acceptable. Today, that boundary for apps is about $5, but that boundary for most websites is $0. Once you’re above that boundary, it doesn’t matter as much whether you charge a few dollars more or less — you’re losing sales because it’s over the line, and it’s almost irrelevant how far over the line you are (within reason)."
