I agree in principle - Discord can only scale that much - imagine having a discord channel instead of docs for Pandas . Obviously it would be best if there were great docs for everything, a lot of easily searchable Q&As + sample projects, and a forum and some form of live chat for the community to discuss ideas.
But those take a ton of time to create, and a ton of skill to write well, and I feel like up and coming niche projects that need to build a community naturally would emphasize Discord over docs.
