There’s a lot of good, free Rails information around. But as you improve your development skills, it can be hard to find knowledge that’s useful to you. If it’s too basic, you’ll just read about things you already know. Too advanced, and your eyes glaze over and your brain shuts off. You can’t just type “intermediate-level Rails blogs” into Google and hope some good sites pop out. To get the information you’re looking for, you’re going to have to do some digging.
