Remember, "Blub" comes from the Blub Paradox (http://paulgraham.com/avg.html) in which one paradoxically believes that his or her language of choice (let's call it Blub) is the overall best language and that others are no good, usually due to missing some particular feature, or that they are too complicated.
An ironic example is that Paul Graham, who I believe is the creator of said paradox, asks rhetorically "If LISP is so great, why doesn't everybody use it?" and later, "I will say that LISP is at the top of the power spectrum." In effect, he's guilty of falling into his own paradox by assuming his language is at the top of the power spectrum, which is no different from assuming some other hypothetical language (that may have more capability than LISP) is too complicated.
