I enjoy articles that do the following. There are people in my team who specialize in this area and know so much more than me about it than I do. We are working on really exciting projects that I don't get the chance as a manger to understand fully under-the-hood, but casual weekend reading just got me closer! It always interests me how much top developers are not just coding experts but also domain experts.

Edit: ps. We are interested in meeting more of those colour domain experts...
