I had the luck of getting to interact with Simon a little at my first real programmer job at Eventbrite. You would never know meeting him that he was one of the creators of Django, (and TIL querySelector!). He was infectiously curious and excited about programming in a way that bubbled over to most people he interacted with. He would also enthusiastically engage with what you were working on, even the beginner project I had at the time. I don't know him well, but my impression was not just of a great programmer, but a great colleague and an authentically positive person.

Congrats on twenty years!
