It’s free and easy to setup. That was the same as Facebook, Twitter,… and that’s because corporations have money to throw at the problem. The issue is that their intention is not the same as the users and after a while, the illusionary cooperation stops. And then, the communities collapse and a whole part of the internet goes dark.

The other part is that Discord feels much more like a club than a library. It may be nicer, but no one is interested in popularizing information. Instead you have to hope to be heard by the experts. And that’s after the requirement of being a member. A forum is open to anyone on the internet, who can consult the interactions anytime they want. And information categorization is already done.

The real danger of Discord is that people want to use it for everything and forget to offer other means of communication like a Wiki or a bug tracker. Imagine if Arch Linux was only present on Discord.

The alternative are still the same as it was ages ago. Host a forum software yourself or pay someone to do it. And build a Wiki to answer the most requested information. Relying on free products from companies is not the correct decision if you care about permanence.
