Creator of Sqwok here, you can have long-lived real-time conversations that will get bumped even if they're older, while also having notifications, @mentions, embeds, following, search, themes (including "hacker" https://imgur.com/a/qHkopKO), etc. The ranking algo is based off live conversation activity.

I did a Show HN back in April and have been quietly continuing to develop the site. Open to ideas/suggestions as well.
