I'm the cofounder of Codecademy. Unfortunately, there aren't comments allowed on the author's blog so I'll comment here (I'm emailing him as well so hopefully my comment gets posted to his blog).

We've received a lot of feedback on our initial courses page redesign since a soft launch on Saturday. We're working on making it easier for our users to find what's important to them and to discover interesting courses among those available on Codecademy.

I'd love to hear everyone else's feedback - we've been making incremental changes since the launch of the redesign (we work all the time) and we won't stop until it's incredibly easy to find the right courses. As the author mentions, we're starting with gradual changes. Thanks for your patience.
