If the problem is that you know what Ruby code looks like but don't feel comfortable enough to build stuff in it: go build stuff in it. Seriously. Just go write some code right now, Google around when you get stuck, and half an hour later you will already be a better programmer.
Do a few http://projecteuler.net/ problems. Just, like, three or four. Bam: You've programmed.
Programming can seem like this big, scary thing; it's easy to feel like you're on the other side of this big huge wall and to say "I don't know how to program, so I can't program." The catch is, the only way to learn how to program is to program, and no in-browser language tutorial in the world can change that. Go for it, and ping me if you get stuck.
I've been learning Ruby myself lately, and I don't think it's quite as simple as "go build stuff in it." Much more helpful for seasoned people to say "take a class, join a meetup group, and get some help because it's normal to get stuck and need help." For someone who's never programmed before, just installing the right software and setting up an environment of any sort is intimidating and easy to get stuck on.
Sure, you need to start building stuff, but RubyMonk, CodeAcademy, and others like them are great ways to get people interested enough to take the next step. We just need some good resources to take those next steps, and Googling doesn't always lead you to a good, accessible resource (I hear http://learnpythonthehardway works for Python, but don't really know of similar resources for other languages).
