Discord Edge and Embedded developers community site more than doubles users

Discord is implementing a forum mode, that would be great if somehow the discord forum post were publicly exposed and crawlable at least

You are right, however many tools are starting to think about this issue. We tested the beta of a tool (https://open.crowd.dev/luos) and they are developing a feature that allows you to publish a mini-website that indexes the most interesting content published in the community. And as seren said, Discord has also recently released a Forum feature to better categorize topics and allow members to quickly find and exchange :)
