Good point. If I did, it would be a sister site separate from this Rotten Tomatoes based thing. I'm trying to keep it as simple and uncluttered as possible.
Thanks, and thanks for the suggestions! There will be some changes to those sliders in the near future. (JQuery was my first choice for those, but it's now proving to be an aesthetic and responsive issue.) I might redesign it with Twitter bootstrap, which would help with overall UI and design.
I second this. Pine's book has good learning flow. It makes you think through programming problems with the tools at hand; it prepares you just enough for practice examples, requiring you to work hard for the answers. This results in a very fun and effective learning process, and a long-lasting knowledge of basic Ruby idioms.
