I think the general level of criticism seems a bit harsh.
It's perfectly usable even under the weight of at least HN, quite a lot of effort has clearly gone into it. There's some edges that want polishing, particularly around page transitions but I don't see much from a quick look or any of the comments that couldn't be resolved in short order. Most of the issues are where they've been a little keen to apply effects.
I'm not sure I'll ever warm to javascript on the server for my own needs, but good luck to them I say.
