For those who are unfamiliar, the default sorting algorithm on most clients is "Hot" - It's intended to be closer to "New" than "Top" so people who come to a thread late can have their opinion read.
However...
I personally find it's too aggressively New balanced. I've seen threads where the "most correct" comment has 100 upvotes, and is 3rd from the bottom with a bunch of less upvoted comments on top. In a lot of ways, this is worse, since a user has to read multiple lower-quality comments before they get the same information.
I'm not suggesting "Top" become the default, or "Hot" become effectively "Top". All I'm suggesting is slightly increase the weight of upvotes on "Hot", so it's not effectively "New".
Agree/Disagree?
The best solution IMO would be "mark as read" (by clicking) that does not show comments marked as read (which is what reddit enhancement suite does.
Its way too hard to keep reading comments in a post you like if you are interested in it.
