I sometimes get asked by regular people in the actual real world what it is that I do for a living, and here’s my 15 second answer:
We built a sort of Wikipedia website for programmers to post questions and answers. It’s called Stack Overflow.
As of last month, it’s been 10 years since Joel Spolsky and I started Stack Overflow. I currently do other stuff now, and I have since 2012, but if I will be known for anything when I’m dead, clearly it is going to be good old Stack Overflow.
