The results for the Stack Overflow survey are here, and I was surprised by one of the statistics. The question was what online resources people use to learn to code. The percent of people who selected Stack Overflow as a resource was only 86.14%.
It seems to me that if you are using Stack Overflow, you are almost guaranteed to be trying to solve some sort of coding issue ("Stack Overflow is a question and answer site for professional and enthusiast programmers." about). There may be a few people using Stack Overflow instead of some more appropriate Stack Exchange site, but it seems to me that such a person would not know/be very invested in Stack Overflow/Exchange, and as such, would not be invested enough to take a survey.
What kind of people, in what situations, would be dedicated enough to fill out such a survey, but not consider Stack Overflow as a resource for learning how to code?
