Love the service, hate the app – Treehouse: Learn Programming and Design Review

I've been a Treehouse user for a several years, and I love this service. I've learned an immeasurable amount, and I've been lucky enough to make a career of web development because of it. That said, the app is just bad. Videos take multiple attempts to load, and quizzes are undoable because of page layout (text of questions is almost always cut off on the right side) on iPhone.
