I knew two friends who have AS. Of course, I only found out recently, and one was a good friend of mine (haven't seen him in a while... I'll drop by his place tomorrow).
The second I hated the guts out of. Honestly, just mention his name and I started getting resentful. He was constantly following me throughout school, and he lived a short way away from me, so he followed me on the way home as well (he also said that the number of power poles between my house and his was 11. I checked the following afternoon... ...he was right). Fortunately, finding out more about AS and it's troubles and all that stuff via the internet, Mark Haddon's latest book, and of course this website, has completely changed everything, and I can tolerate him a lot better now.
Apart from that, the only other person I suspect to have AS is my sister, but that's just because she's just plain weird...

I was sad when I found that she left
But then I found
That I could speak to her,
In a way
And sadness turned to comfort
We all go there
