I think it's starting to go the other direction. As a technical-minded person if I have a business meeting and the other person starts throwing those yuppie buzzwords in my face I'll just mentally put them in the "empty suit with an MBA" bin.
It might be my Southern European sensibilities, but I value straightforwardness very highly than time wasting nonsense to signal you're part of the in crowd. Unless the hacker ethos has died, and we're back to the 1980 where middle managers in business suits are the cool guys.
