Quoth It's me
Grammar Girl podcast on how us Canuks really pronounce certain words... what I found really interesting is her explanation at the end of the podcast on why people think we pronounce "about" as "aboot" etc. when in fact we really don't.
Probably the same reason Americans pronounce "floor" as "flaw". Hey, what do you mean people in Brooklyn, Michigan's Upper Peninsula, Georgia, and Texas all have different pronunciations?
