Indeed. Python is my Blub; it's just so darn easy and it has enough functional capabilities that I haven't yet felt compelled to throw out everything I know and start with Haskell or Clojure.
The interesting thing about Blub programmers is that they do not know they are Blub programmers.
Even more interesting: Even those who know about the above phenomenon and make meta-comments on it are Blub programmers and do not know that they don't know this. </mega-irony>
I am a Haskell programmer, and aware of the more powerful abstractions available in Agda and similar languages. So I am aware of my Blubness :-)
But I try to keep up to date with regards to PL technologies, so I think I'm closer to the top of the contemporary Blub ladder, but I guess any Blub programmer might think that!
