A difference between Talkyard and Discourse, for blog comments, is that Talkyard is threaded, like Disqus. So when people start talking about different things related to the blog post — start different "sub topics", then, with Talkyard, each such sub topic gets its own sub thread,
... Whilst with Discourse, all sub topics are mixed together into one single flat layout.
And, with Talkyard and Disqus etc, the more interesting (more popular) sub topics are shown first, whilst with Discourse, it's whoever happened to type the first comment, who is shown first.
