Ask HN: A developers opinion of Treehouse

Hi all, I love web apps and want to start to build my own. ive been doing graphic design and motion graphic work for years and have purposefully put off learning any sort of code because i think its better to make money doing something you love and pay someone to do something you dont. But recently I've decided that I need to bite the bullet and learn how to code (HTML,CSS and rails) looking at a lot of the training sites out there I'm leaning towards using Treehouse. I was wondering who else has used it and if any developers have used it would you recommend it? Thanks
