Staying aside of the debate about the selection critieria for Worlds, I just wanted to say few things about Rachel Flatt.
I already wrote in the SP thread that this was the first time I saw her on TV (youtube before), and to me she seems to be very musical, delicate and artistic. She really feels the music and relates to it. She adds 'something' from her heart to the programs (this is something that IMO Caroline Zhangs is not able to do. Even if she improved her artistry a bit, everything from her seems 'learnt' and a bit fake). Back to the topic - although Rachel's program was not superb yet, I have a feeling that she will be able to blossom very soon, and become as mature and as special as Michelle Kwan became all of the sudden in 1996. I keep my fingers crossed for Rachel!!
PS She should work on her posture, though. And on 'styling'. Her dresses need something more personal, something more 'Rachelish'.
