I'm surprised by the popularity of English accents - I suppose I'm used to them, so they don't hold any allure for me. I generally think of myself as 'accentless', just a bland southern English accent. Not interesting at all :-/
I like the accents that people from Scandinavian countries have when speaking English. We have a few Danes and a couple of Norwegians in my guild so it's nice listening to them on TS.
Also really like the accent from the south of the US, a bit of a southern drawl sounds really good to me.
