I have used HackerNode for the longest time. It has some weird UI elements but for some reason I like the way it uses the screen space, all the other seem to involve a lot of scrolling (more than I personally want) Sadly recently HackerNode's comment section broke and none of the ASK HN type posts render any more. So I guess what I'm saying is, I'll give it a go :-)
