I find it mildly irksome that Hacker News readers often assume that blog posts are always written for someone like them - i.e. someone unfamiliar with the author who happened upon the post without context. That used to be the way blogs work, just written for a broad, unknown audience, but these days most blogs are written with a specific audience in mind, often one that knows the author reasonably well. Sometimes the blog is even just a secondary place to have an archive of the post, the main intended place being a post on a close-knit forum. Once you take away the assumption that you're the intended audience, it's much easier to see the article - and the things it says and doesn't explicitly say - in a clearer light.
