What works one way works the other. You cannot say that someone sound intelligent due to their accent and not at the same time conversely be implying that others sound airheaded due to their accent.And anyway, it was meant to be a compliment to Little, not a cutting remark at all the other girls in England.
Besides, without meaning to imply anything myself, for what I heard of the first five minutes that I could bare to scrape through, there was no evidence of apparent intelligence at all considering that both hosts conceded that their "opinions" were, in both cases, paraphrased from other forum members. Which is the same point at which I concluded that this wasn't adding anything that isn't already available via the forums anyway. I think that for the podcast to be more successful, it would need to have some kind of exclusivity hook. Not that I am formally proposing that, because then I would actually have to listen to it ;p
