>What comes after Stack Overflow?

Codidact (https://software.codidact.com), for those who actually care about the Q&A site model (although we're designed explicitly to allow for opening separate "sections" for things that don't work like Q&A). That is, if you're posting a question in order to frame useful, searchable information, and not simply to get help with a project.

Disclosure: I am a moderator there (actual moderator, not just someone entitled to edit posts - which we still do as a community, with the same kind of Creative Commons licensing arrangement).
