I personally have a strange relationship with Stack Overflow. I didn’t know it has only been 10 years since Stack Overflow was launched. This means that most of my studying career I didn’t have Stack Overflow, and I was not looking there for answers.
To be very frank, still to this day I don’t have an account on Stack Overflow, I have never asked any question on it and I rarely find any useful answer there. The only time I find useful answers is when I’m using a programming language or a tool that I’m just a junior at it and I ask a very dumb question with a very simple answer. Most of the times now I get better answers searching on the GitHub issues of the project I am using, or on some random blog on the internet, not really on Stack Overflow.
This article has an interesting overview of Stack Overflow, that I have never seen. One of the most interesting things I found out is that Stack Overflow is considered mostly a Wiki from the founder, and you (even anonymously) can improve the questions and the answers, to better explain it for future people that will look at it. I really never thought about Stack Overflow as a Wiki, but only as a Q&A, which has been very well indexed via Google (as mentioned in the article, 98% of the visitors gets their answer via a search, and never ask questions on Stack Overflow). I would be curious to know how many people are actually improving questions or answers in Stack Overflow, but this information is unfortunately not mentioned in the article.
The article, in general, doesn’t even answer the question of the title. Looks like Stack Overflow will not change that much in the coming 10 years, which is not something I’m very happy about. As mentioned previously, as a more experienced programmer I don’t find much value on it, and looks like the more complex questions are not asked there (also because a more complex question and a more complex answer require more than a simple Q&A website). I think it still is a great resource for a junior programmer to get their answers (even without asking any question), but I would have expected and hoped that would change in the coming 10 years, to become more useful also for a different demographics.
