I think there are those who don't mind her and those who won't watch her. I fall into the latter camp.
There are no other QVC presenters that I absolutely can't watch.... even bellowing Simon ANNNND!!! Biagi (though he does run her a close second).
I do watch Debbie (usually on mute) just to see her latest fashion disasters).
My league table for female presenters is biased towards non-tweeters... so for me Anne Dawson is now #1 - she's well groomed, representative of the customer, lets guests speak - practically perfect! Jilly is catching the tweeting disease. Julia Roberts is turning into a hybrid Debbie Flint-Jill Franks and therefore is plunging down the league table for me. Flicking hair and flirting with camera and presenters; endless shameless plugs of her books; pointy finger; "humourous" sarky comments aimed at guest and/or studio team; pointing finger; inappropriate (and downright ugly a lot of the time) footwear... plus her own special trait - "I'm a size small" (yes, in your dreams Jules...)... Kathy has shocked me recently. I've seen her a few times being downright rude to the studio team, models and even guest. I used to quite like her.
The problem now is "be careful what you wish for"... as we will probably get landed with more strident harpies instead of more professional and measured presenters. Although the QVC strategy seems to be to turn as many of the existing presenters into harpies.
