Deceived Pronunciation

Not really Poetry, Poetics, or Portland, but I'm intrigued with aristo Sam Cam's down-class accent being pegged as "Estuarial."

Estuary English was first identified as such in 1984. Am I alone in noticing a distinct under-40 accent that's taken root here? A sort of regionless softened Valley one, ventilated with actuallys, where most clauses swoop up into questions, and the vowels lodge high in the nose? So common that you don't even think of it as accent anymore, just assume when you hear it ...
