>Pick any OS and if you've never used it before you'll run into quite a bit of cognitive dissonance when trying it out for the first time. That's the author's point. He's parodying the myriad 'I tried Linux, and it sucks' blogs that have been around since forever ago. Since he knew that large sections of the internet have trouble with subtlety and sarcasm, and wouldn't get that without him saying so explicitly in the text, he said so explicitly in the text. Which would have helped if there weren't also large sections of the internet that are prone to commenting before reading the text.
