Codecademy is an interesting link. I'm not sure why most people would want to learn to write in code, but I do believe that this is a good way to learn it. I was enjoying the 10-15 minutes I had playing around with the tutorial, but I'm probably wired a little differently than some. In working on this site, I did learn and have a bit of a refresher on items I had worked with in the past. You might want to check it out.
