My comment mentioned mainstream languages. To my knowledge, Brainfuck is not a mainstream language used at any small, medium, or large corporation.
The point about the spec was the language is small enough to master.
Scheme (Lisps in general) is different because it is homoionic. Forth is not mainstream, and neither is it's paradigm. And well, I never heard of Io so I will check it out, looks neat.
And your point was refuted. Brainfuck not being mainstream is irrelevant; either a short language spec correlates with speed and easiness of mastery or it doesn't. And the counter-evidence shows that it doesn't.
You can't just casually ignore inconvenient exceptions to your beliefs. I mean, you can, but it's not something that reflects positively.
