Mort/Elvis/Einstein: The Humpty Dumpty Personae

There's been a rash of criticism about Microsoft's Mort/Elvis/Einstein personas. A few months ago, I swiped at M/E/E and triggered some correspondence. Part of that was the surprising lack-of-results for a search for a document that defines the Mort/Elvis/Einstein personas! One certainly justifiable criticism of M/E/E is that they (especially Mort) seem to mean whatever the speaker wishes them to mean, just as for Humpty Dumpty. Does Mort program in more than one language? Is a former C++ programmer who's now a product manager a "Mort"? Would Mort use a DSL if one was available? I think the answer to these questions is, "whichever answer furthers your argument."
