"Blub programmers" are referenced in "Beating the averages" ~ http://www.paulgraham.com/avg.html and describes the "Blub paradox".

   "... As long as our hypothetical Blub programmer 
   is looking down the power continuum, he knows 
   he's looking down. Languages less powerful than 
   Blub are obviously less powerful, because they're 
   missing some feature he's used to. But when our 
   hypothetical Blub programmer looks in the other 
   direction, up the power continuum, he doesn't 
   realize he's looking up. What he sees are merely 
   weird languages. He probably considers them 
   about equivalent in power to Blub, but with all 
   this other hairy stuff thrown in as well. Blub is 
   good enough for him, because he thinks in Blub ..."

Raganwarld has a good explanation of the "Blub paradox" ~ http://weblog.raganwald.com/2006/10/are-we-blub-programmers....
