Feel free to comment on the blog, too, but I wanted to open this up to a fuller discussion here as well:
The principles in the default Discourse community behavior FAQ were distilled, as best we could, from the common, shared community guidelines of more than 50 forums active for a decade or more. We hope that anyone can launch a Discourse-powered forum community with confidence, knowing that they’ve got the basic guidelines for civilized discourse covered.
I’m not sure we got it 100% right, and every Discourse forum is completely free to modify these default guidelines in any way they see fit. But we feel the current guidelines are a giant step forward for online discourse, and do justice to the concept of the Civilized Discourse Construction Kit we set out to make.
We view the community behavior FAQ as one of the most important things we ship – you can’t have civilized behavior without some basic shared guidelines that everyone follows.
