Tutorial Feedback required : Interactive way to learn Android using Eclipse plugin

Hi,

I am part of Codelearn.org.
We have created an interactive Android Tutorial where you learn android online, do it in your Eclipse IDE and a plugin which tests your progress and helps you with non-trivial errors .

I would love to have feedback from you guys over how helpful it is for a newbie or a person who wants to brush up his concepts.

You can try it here at codelearn.org/android-tutorial
