At first I "hated" the 50 replies per screen change. Seemed too convulted when you wanted to see what people were replying to. But I have come to see it as a good way to manage long threads.
I avoid alot of the "dumb" threads but some of them are pretty darn funny - still love "How many FReepers does it take to change a lightbulb! But when you want to find the "real" news, I think this is gonna help. They're also working on topic management which I think will be great.
