Thanks, Casey, for coming back and demonstrating that intelligence and 
politeness are not mutually exclusive. I encourage people who haven't 
read your article linked above to do so; it contains some excellent and 
concise explanations of the rationale for civil treatment of beginners.

One more explanation that might help was given to me by the founder of 
the O'Reilly School of Technology, who I am creating courses for.  He is 
very enthusiastic and inspiring about education, and wants to make sure 
all the OST courses follow his vision, and he recognizes that expertise 
is not the same thing as teaching ability, so he impressed upon his 
authors the following model.  

He breaks down students into a bell curve.  On the right tail are the 
early adopters like Randal, me, Uri, Casey, and other experts we could 
all name.  These people will learn something, anything, and everything 
without any external prodding; they just go off and hunt down the 
resources, read the manual, experiment.  They're completely self-starting.

The middle of the bell curve - where the most students are - contains 
people who learn better with varying levels of help and encouragement, 
ranging from a point in the right direction to more directed help from a 
mentor.  OST courses (and Stonehenge, etc, courses) are for them.  They'd 
be a waste of time for the people on the right tail.

People out on the right tail are particularly prone to thinking that the 
best or only way to learn is the same way they did - self-motivated 
figuring things out from the manual and experimentation - and that any 
other approach is inferior or wrong.  But it's simply not going to work 
for the folk in the middle of the curve, who learn a different way.  Some 
folk on the right tail think that if they beat up the people in the 
middle enough, they'll migrate to the right tail - where the "right" 
people are.  Any instances of this actually working are so rare as to be 
the exceptions that prove the rule.

Note that this is a bell curve of learning types, *not* intelligence or 
ability.  And as other posters have pointed out, someone can be in the 
right tail in one discipline, like bioinformatics, and in the middle in 
another - like Perl.
