Gregg here from Code School.. we actually tried making it autoscroll down at first. It was too distracting and annoying. Scrolling down when you're ready to continue just felt more natural.
Many great points Jyri. This course certainly is not meant to be a completely detailed introduction. At Code School we're in the middle of working on something that should be more of a step by step introduction.
However, I think there's something to be said for showing people how they can be immediately productive with a tool before really understanding everything that's going on underneath. With just a few commands someone can start using git successfully, and that's all we were trying to communicate with this tutorial.
Nope, it needed a rewrite. We talked to Andrew who was hosting and helping maintain it, and he expressed interest in getting help. We did our best to stay true to _why, keep the same content, and keep it free.
Only real difference now is you have the ability to save your progress as you go using your Code School account. If you don't want to, you don't have to. =)
Sorry for the slowness. We were having issues with traffic earlier that didn't have much to do with Ruby, but it should be MUCH faster now. Let us know if you run into any other issues.
Hey Andy.. looks like you were playing through when we hit a spike in traffic... However, things look like they're back to normal. Let me know if it's still slow for you.
