Dipankrispaneven - ooh someone else who loved Austin's jive. Austin woz definitely robbed ! 
Maybe people are voting for Anton in the desperate hope that if he wins he will go.
I think Jay's got a goodish choice for semi final week - those dances aren't too complicated in terms of steps, so more time to make a good performance.
I think the ''previous dance experience' thing is a bit of a red herring for all of them. There have to be some people in it who can dance - otherwise there is a risk of all Anne Widdicombes - and there would be no show.
Dance experience is only one kind of relevant experience for this show, I'd say since most of the public aren't dance experts. Performance/acting experience is a bigger advantage - you can bluff your way through a lot of lack of technique if you know how to perform. Sportsmen have the fitness advantage and the disciplined approach and work ethic, TV presenters are used to talking on camera and knowing what to say and how to present themselves as a non- offensive character. It's all swings and roundabouts really.
I remember Colin Murray being on a singing thing once (think it was comic relief Fame academy) and him saying he knew what his listenership was in terms of numbers and if they supported him he would come fourth (or whatever it was) and he was right. So some people come in with an already established fan base, or number of people that watch their programme on telly, and that's a big advantage too.
