Johan, I'm sure I speak for everyone at Sage Tree Solutions when I say "All the best, and many thanks!" You've been such an amazing contributor to the Drupal ecosystem, and I have personally learned so much from your efforts. I'm sure I'll continue to do so as your library of videos is so plentiful.
I'm sure you'll continue to share what you discover in your teaching, at least with your students. If news leaks outside of your school, know that there will be many interested to hear what you find.
