I think she's great at her job and she definitely has a unique look that is her own rather than contrived.
She seems to attract far more criticism than other models which I think is unfair. Whatever she has done in the past, she is not the only high earning person with a dodgy private life.
As for the question over how hard models work: it is bloody hard work. I work in fashion and it is unusual to get that "ultimate" picture in a short time at the level of editorial perfection that Vogue and other glossies demand, even with the likes of Testino behind the camera. You can't have a fat day, a feeling crap day, a "not in the mood, frankly" day. You are scrutinised, poked, prodded and criticised all as part of your job. Yes, the money is ridiculous but then there are examples of unfair pay scales all over society. Doesn't make it right but that's capitalism & consumerism for you.
As for the weight issue: the designers themselves need to take a lot of flack for that. The designers choose which models they want to represent them. Until they start voting with their feet and steadfastly refusing to use underweight, unhealthy models then the system will continue as it is. Having said that, I disagree that you need to starve yourself to maintain a model figure. It isn't necessary to be waif-thin to be a successful model. More athletic figures also make the cut (Giselle, Naomi Campbell, Lara Stone, Doutzen Kroes...).
I'm waiting to open my copy of Vogue until I have done the school run and have a cup of tea in hand. However, I did watch the video interview which I thought frankly was more Vague than Vogue. Shame as I do think she comes across as a laugh and more down to earth than you would think. That also seems genuine, unlike Naomi Campbell who always seems to be desperately try-hard and fake self-depracating (sp?).
