I agree with @qriouslad:
Well thought out UX, and very focused on fostering, well, ongoing discourses.
Two of my favorites feature of Discourse so far:
- That reply count (7/20) which updates itself when I scroll down the page so I know the length of this thread, and how much stuff that can be read left
- Markdown + previewing when I’m typing a reply so I know how my reply will look like
Regardless that two features, the UI of the Discourse feels clean, familiar, and “right” too.
One thing I don’t quite like tho: the logo of WP Chat looks like something we saw everywhere on 2004. Glossy icon feels too web 2.0-ish, IMO
