It’s got some good ideas but you lost me at once they vote they can sort by most popular comments. So users only get one vote ? Also how do you stop the sorting before vote the sort happens at the app level or browser level. If I have all the comments via the api I can’t sort and nothing can stop me from doing so.

But I like the other ideas I also think it would be good to expand to 3 types of threads the two you listed but I would use technical vs normal and add a serious type for non-technical threads.
