I may be a rare-bird type of user on StackOverflow. I started using StackOverflow to ask primarily ask questions from the earliest days, I have an ultra high reputation, my question count dwarfs my answer count by more than 3:2.

My answer to this question is that I simply got better at solving programming problems on my own without having to ask for help. That increase of skill coupled with the the overly aggressive moderation that acted as a deterrent for me to ask questions has led to a point where I have practically no need for the platform.

I have even noticed that I will typically bypass stack-overflow when researching a problem, preferring other resources first (official documentation).
