I'm a programmer who has used codecademy (not sure if you're talking about codecademy or codeacademy as they're two different entities) and I really enjoyed it.
The site won't make you a world class hacker, that's for sure, but it will give you enough skills to know what to do next.. in order to get to the world class hacker level.
I recommend picking up a programming language while you're using it (might I suggest Ruby?) If you do decide to learn a programming language, regardless of the language, you learn a LOT by taking your skills and applying them to the dumbest sounding, most menial puzzles. Believe it or not, you can learn a lot about programming by making a program as simple as one that prints the lyrics to "99 bottles of beer." The goal is to get lots of logic involved in the code, so the code is very concise.
Good luck! Programming is awesome!
