I suspect that if you want to know about Arc's design goals, then pg's writings at http://www.paulgraham.com/arc.html is a better source than various random interpretations floating around on the forums.
Agreed. I do hope, however, that arc.v4.0 is structured in such away to move away from being news.arc centric. I hope pg chooses a different project to push down on arc. I think this would open the door to a fresh perspective.
