Good point, and I think there isn’t a one stop shop. But I think chat is overrated in this, it might be an addition. But having information that is not search indexed limits access and thus usability for the broader community. Also discord sucks for KB and FAQ in terms of formatting and setup (usually you see locked chat channels for that containing links to external sources. And the community discussions usually end up with multiple simultaneous discussions that get drowned out by new discussions in the same thread.

I think discord has a role. But it is not a good solution by any means. Lemmy, reddit, even the steam forums seem better.
