With such cultural diversity here in Melbourne, we get such a variety of Englishes. I think I have the hardest time accepting "Bogan" speak, it just sounds so wrong. I don't care what qualifications a person has, if I see doctor and he comes out with something like "Gidday cobber, wats da matter wif ya?", I won't be sticking around.
Edit...Speaking of VOAO, I haven't had any more participants in a while :-(
