What you get as a wiki reader is access to people who had no voice before. - Ward Cunningham

The code might be organized in a hierarchy, but the solution has more dimensions than will fit in a hierarchy. So when you discover a solution in a dimension that crosses across the hierarchy, you just have to go where the solution takes you and put the solution in.

A wiki is always in the process of being organized. But for every hour spent organizing, two more hours are spent adding new material. So the status quo for a wiki is always partially organized.

A wiki is a work sustained by a community.
