hi alex23,  please don't be silly.

Who is being hasty?  How do you know its a generalization?

My comments here are not in the least hasty, nor are they 
generalizations. They are based on long years of experience with 
"normal" users, personal programming experience for almost 40 years, and 
insight into student perception from reader comment forms, evaluations, 
personal discussions. (sometimes from this list mind you)

It is *always* pertinent to ask, "how will this be perceived by the 
user," ehem, going all the why back to Immanuel Kant who was the first 
person (philosopher) to suggest that perception is reality.

Frankly, most of the time when I "claim" to have comprehension from 
someone other than myself its coming up with the answer to that stellar 
question (often in context with community discussion). This all amounts 
to a value add (intelligence) for community, and for comp sci.

Thinking out-loud about community perception is always valid.
