This is entirely unsurprising. This is the strategy that many commercial writers employ, those who want to make a living out of it. They follow reader trends, and keep feeding the trend. I for one don’t like doing that. Having said that, I also don’t care much about the income I make from writing. My goal was just to make a MacBook Pro’s worth in a year so I can keep buying the latest one every year, and that I have already achieved by writing about the stuff I care about. So, I’m happy. 🙂
