I love opinionated articles about tools, processes, and methods. I like to read "This is my favorite because..." and "I hate this because..." instead of "Here's an objective explanation...". I find these the most interesting to read and also the most helpful in forming my own opinions.
I'd also love to read about other developers' journeys—how they got to where they are and how they're getting to wherever they're going. What were their pivotal moments? What are they working toward?
