Lemmy could be that, just have programming (and other) Q&A communities here.
Lemmy is like Reddit, which is used a lot to ask questions and get help. But StackOverflow fills a different niche, it's meant to be useful to as many people as possible and stay up to date. This is why
there's a distinction between "comments" and "answers" (comments can be used to request additional information, and for meta discussion)
both questions and answers can be modified by other users, for example to
add more information, or remove unnecessary details
correct outdated information
fix typos and formatting
rephrase sentences that are confusing
a question can be closed as duplicate, so people always find the oldest thread of the question with the best/most detailed answers
before submitting a question, you get a list of related questions to avoid creating a duplicate question
questions have tags, making them easier to search for
I haven't used Stack Overflow in a while so I forgot about most of those features, and as long as it also uses ActivityPub it doesn't really matter that much if it is a different platform. I think some of those features could even be useful on Lemmy (tagging posts would be nice and maybe community-editable posts could be a thing that communities could choose to enable).
