About 30 years.
I've specialized in making and using tethered target Forths for micro-controllers for the past 20 years or so. I enjoy meeting with like-minded people, sharing my ideas and hearing theirs. Very stimulating.
The Arduino Day meeting was great. Disclaimer, I was one of the speakers. There are always interesting people to talk to who tend to share the notion that simpler and smaller is better. Hard to find such people elsewhere.
