It's got a very strong design which you executed well. It's quite polished. The rails part is hard to comment on because we can't see your code - but from the url structure, it looks like it worked well for you.
Having said that, I'm not really a fan of the design overall because I find it distracting from the actual content. IMO, effective design should help to focus the user's attention on the content, not be part of the focus in and of itself. I'm just not a fan of overly skeuomorphic designs in general for that reason.
The Tips & Tricks animation on the sidebar is also very distracting.
That scripty font renders very thin and isn't very readable for me on chome-stable Win7: http://i.imgur.com/FC5oE.jpg
