The average guy is not interested in knowing all details regarding  
how to
play tennis with a wooden racket from the 1980s, just around
the time when McEnroe was on the tennisfield playing there.

Most people are more interested in whether you can win that grandslam
with what you produce.

The nerds however are interested in how well you can do with a wooden  
from 1980s,therefore projecting your own interest upon those students  
will just
get them desinterested and you will be judged by them as an  
irrelevant person
in their life, whose name they soon forget.
