I hadn't heard of this one before, I'll read up on it!

The Netvyne extension does have a live chat tab as well by the way; its definitely a different experience with live chat vs comments. For sites that a lot of people are on at once, like when a big platform goes down and people go to the official announcement, there could be quite a buzz.

Would the messages in these chat rooms disappear if you left and rejoined, or would you still see a full history?
