This is explained very well and makes each step easy to understand. It's not the best way to do it, but it does explain why gradient descent is awesome and how the intuition works. Hopefully future posts go into greater detail about gradient descent and linear regression to do things more efficiently and faster, but for an intro post, this is most excellent. Well done.
