As someone who only ever asked or answered a couple of questions, Stack Overflow has been on the way out for close to a decade by now. The website never (from my inattentive perspective) did anything about the key problems of a question site:

- If something was marked as a dupe by mods, that was it. There was no way to suggest that a dupe was marked in error on your question or others.

- The site had no standard mechanisms for separating questions in time or by version. So many answers for "python 3" that answered for, like, 3.8 or whatever. Same for operating system and basically any other contextual category.

- Following answers was incredibly inelegant. Would you like to know if the chosen answer switches? What about if there is a new answer for the next version of the software? Trick question we don't track software versions!

- The community had an extremely high learning curve, I think in part because the site had so few affordances. It was very easy to be rude on accident and it left a bad taste in ones mouth.

- The site decided to entirely ignore meta organization. Do you want a category of questions that are kinda silly? What about separating highly complex questions or debugging particular errors from general questions about how to use the tools? Nope, we're not going to do any of that.

I am shocked it lasted as long as it did.
