This is very interesting. Just by skimming the texts, there's a noticeable difference. Matt's paragraphs generally start with "So I..." or "So you/we.." and it's possible to grasp the overall flow of the logic even by looking the beginning of each paragraph, whereas gmaxwell/jgarzik often starts with statements like "This is..." or "I think..." where the relation to previous paragraphs is less clear. Thanks for sharing this.
