There is a lot of hope for people diagnosed with Asperger's. Yes, it is a less severe form of Autism, but never listen to what the skeptics say. There are many accomplished people in the world with Asperger's and there is more and more being learned about it every day. One that comes to mind for me is Dr. Temple Grandin, a very accomplished public speaker on the subject of Autism and Asperger's (who actually has Autism, the more servere of the two). Here is a link to her site.
http://www.templegrandin.com/There are people with Asperger's who have become doctors, public speakers, authors...the list goes on. Many actually have above average I.Q. The biggest challenge is learning social skills and being able to fit into society. You could see this deficit on the show in Heather.
When Heather had her interview in front of the judges they said hello to her. She replied "Hello, pretty ladies, and Tyra". Of course it was not just the words, but the way she said them and body language. Of course when comment was made about her reply, she fell all over herself appologizing.
