As an Aspie, and someone who has done a massive amount of research on Asperger's, I found the whole idea that somehow those with Asperger's speak really well a misconception. It all started because of how Hans Asperger observed in a group of boys (which is how he coined the diagnosis of Asperger's Syndrome) that they they spoke very pedantic.

I'm sorry if I sound rude but I dislike being informed about things I know much about. As another Aspie I think you will understand. But what you have stated is actually not as true as a lot of people think it is. If you want my honest opinion I think these misconceptions are pushed by the parts of the autistic community that want to somehow prove they are "better" than neurotypicals. I'm guessing this is because of the fact they have probably been made to feel inferior most of their lives and incompetent, not to mention a group bias effect.
