Today is the last day of CodeSchool. As reaction I deleted my account.
Too bad, since I liked the interactivity of it. 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.
