I don't really understand why this got 100 points. It's a passably good presentation, at least for the first half, but serving it out as a pdf was silly (why not just upload it to slideshare if you must share it in slide form?) and it really degenerated into randomness as it progressed. It's alright, but not good enough to deserve top spot on HN for hours. Maybe it's just a really slow news day for HN.
