If much of your development is spent on implementing business logic in a language you are familiar with, and you have a decent IDE, I don't know what you use stackoverflow for at that frequency. Occasionally you may need to consult stackoverflow for a specific issue in string manipulation or API usage, but that's not something you run into a lot.
I rarely ever need to use SO on a daily basis. I've been programming on the .NET ecosystem for a while now and usually if I need anything I just directly go to the docs.
I used SO a lot when I was a junior engineer. Most of my issues now stem from biz logic or internal design that really can't be googled for.
