I love exercism. It's beautiful, works in the browser and from CLI. The lessons are really well designed. It's the perfect coding school environment.
So, I'm sad it isn't viable.
But, I think I am really saddened by the comments here, second guessing all the decisions they made. If I were to second guess the people behind most of the comments, I would assume no one has ever run a business with payroll, or built something with this much reach. The comments ring really hollow for the most part and seem really callous given this person has sunk his life into making the world, and my life, a better place. I'm scared for the moment he is in life and sad there are not more positive comments, and even better, comments from people where they would actually help by making a donation.
