Agreed. But having one place to check before reaching for StackOverflow is nice. The other thing that I find interesting is that when I'm hitting into an error I want it to go away ASAP. But if I read a collected list, an error I don't understand immediately gets my attention. So I think it's an nice way to learn something.
