I just don't understand the issue people are having here. Nested callbacks are a design choice, if you do not want nested callbacks stop writing code with them in it.

Here is a simple example in some Node.js code I've just written (I've never written any before this little project).

As you can see you just need to write in an OO manner and use function.bind(this) and Bob's your uncle. Really don't get the difficulty.
