At the moment everything is in-order, when in reality few will want to read through in its exact ordering. The front-end should allow people to pick and choose what they want to read next. Each node should have hints as to its prerequisites.

Chapter 2 is way too long and non-specific. Splitting it up into a "Standard Patterns" folder could help people like this guy, who just want to know how to perform one simple task like allocating a dynamic array, by making the right guide easier to find.

@tecanec Do you have any more concrete ideas?

The main annoyance for me was and partially are the &[_][]u8 annotations for strings, but other than that everything in std.mem is relative easy to pick up from the tests.
