Hi, I am glad you are creating such application, it seems really interesting. Here is more info about the app, we are about to build:

- the evaluation of the progress is going to happen by running it against tests written in advance and against tools that evaluate code quality. The algorithm that is going to calculate the exact percent is yet to be created.

- user experience is the most important thing for me, if it is good and not intruding, it will help developers to stick in the application longer and learn more things (I guess)

- my hope is that the content (best practices and exercises) will be constantly updated and written by the best developers in the field or by authors that will be specifically chosen for that purpose
