Both of those platforms are making answers harder to find. For me, a person used to getting the correct answer in Stackoverflow right away, scrolling through endless GitHub discussions is a nightmare. Aren't we just moving backwards?
SO lost it's appeal, can't say exactly why, but it often has outdated content. I cannot say I get the correct answer there right away.
Each platform fills different role, GitHub is project specific and access to maintainers, who do not monitor SO. Discord is chat, with maintainers and community. SO misses the connection to the people building and using the software, it's more like the Quora of software nowadays. That Discord and GitHub have terrible search is not detracting from their other benefits
