There was a lot of interesting discussion on the previous submission: http://news.ycombinator.com/item?id=2346590 http://news.ycombinator.com/item?id=2346590 Robert Harper's tone seems to rile a lot of people up (some might say he's aggressive, but I would instead use "enthusiastic") and he seems to pick really flame-baity titles, but I'm really glad to have found his blog. It's usually thought provoking stuff.
