Better Explained

I don't know if Better Explained qualifies as a blog, but it is updated periodically with new posts, so I'm mentioning it here. Better Explained takes a boring subject that you learned in school and presents it in a new, more intuitive way. It also let's you think about the topic in ways that boring class lectures didn't present. Topics on the site are geared toward math, programming, and business, with a smattering of posts on other subjects.
