I'm an older Brit from up north. I work as a maths teacher. Originally, I stumbled upon your blog when looking for ideas for a smart home when I investigated a specific problem. Can't remember what it was. I am into techie things and love making things better or more efficient or more user attainable and so on so some of your ideas about user interfaces occasionally pique my interest. Some things are way out of my comfort zone and I usually stop reading after the first line in all honesty. At a guess, I think I would have probably read about 25% of your content.
