Discourse is the 100% open source, next-generation discussion platform. You should consider using Discourse when you need a mailing list, a forum to discuss something, and a chat room where you can type paragraphs.
Discourse is a from-scratch reboot, an attempt to reimagine what a modern, sustainable, fully open-source Internet discussion platform should be today. They tried to build the community that has a natural immune system to defend itself from trolls, bad actors, and spammers. There’s also a trust system, so engaged community members can assist in the governance of their community.
The act of participating in a discussion should fundamentally feel good in a way that it currently does not on all existing forums and mailing lists. It should be fun to have discussions with other human beings, not a chore, or something that’s barely tolerable.
