Today is the last day of CodeSchool.
As reaction I deleted my account.
Too bad, since I liked the interactivity of it.
However, I didn't took a course in two years!
Most likely because I learned from book in that time...
The future of CodeSchool consists in
courses of its new owner, Pluralsight.
In my experience almost all courses are paid-for only.
That's bad for casual learners like me.
So I will look into alternatives like Codecademy,
Khan Academy, Udemy or
Treehouse.
