Crashes a few times upon initial loading. Had to refresh. After it did load, I find the examples are much harder to read than helpful. There are a couple of Chrome plugins I currently use for hacker news for helping identify new comments as well as collapse comments that works out well without having to leave the actual hacker news site.

Those are the ones I use and they work fairly well. Of course that doesn't actually help stuff like iOS browsing but it doesn't bother me too much.
