   Other than Quora, it's like the only one on this list that actually plays the same role Stack Overflow plays. It's a reputation-based question and answer site (or collection of sites/communities) organized around a central topic

   Codidact implements features that are impossible on Stack Overflow, based on what the community needs. The community is central on Codidact and the platform is open-source, so you can use Codidact's network or set up your own if you want to run things differently.
