You Should Use an Outliner

Dave Winer on why you're crazy not to use an outliner :

It's just a tool, not a religion, or a cause, it has no mystical properties. It's just useful. Like you use a hammer for some things and a screwdriver for others. It's also easy to use. Text on rails.

Well, crazy is a bit harsh. But he does make some good points. And yes, Dave, I do use one!
