Harry Potter and the Methods of Rationality finished today
I'm seriously surprised at how many people here are fans of Yudkowsky, given his lack of any real productive output beyond thought experiments and fanfiction, the distinctly weird stuff he judges as right by taking his philosophy to the extremes (e.g. "it's better for one person to be tortured for fifty years than for an extremely large number of people to each get a speck of dust in their eye"), and the way he treats certain fringe positions as absolutely true despite the lack of any solid evidence to support them (for example, many-worlds theory).
