"professional kiter" is definitely a word that means absolutely nothing. In real sports the companies that you ride for turn you pro and "going pro" is actually a big deal. In kiting everyone just claims they are a pro, when really pretty much everyone would be considered an AM for the company they ride for in any other sport.
That first vid was rubbish. Wow, she's got a nice ass... so does a whole heap of other girls... hey guess what, you can even see chicks with no clothes on on the internets to nowdays... did anyone know that?
Bruna is rad. She can ride really well from what I have witnessed in real life and she is also one of the nicest girls you could meet and she can look good to. Womens kiting is only going to get somewhere when companies and girls take the sport seriously like Bruna, Karolina etc. Until then it's still going to be a joke (pretty much like the rest of the sport).
p.s. What about some more footage of Nina H? (now Nina J)

Now that was a girl who could kite and look good! I'm pretty sure the reason she could do those awesome raleys was because she was so top heavy haha.
