Not so much "excited" as "interested": it's 30 years old, and just ask yourself how many OSs and CPU architectures and development environments it has been ported across while retaining some degree of continuity. I realize most folks on HN trend young and are always interested in the latest new hotness, but here's a tool I remember from when I first began using Macs (in the early 90s) and it's still with us and under active development, unlike the overwhelming majority of hobbyist software projects. There are lessons in here.
