I met an aspie on a dating site once. He was from Florida or somewhere though, and didn't seem interested in actually dating as much as just finding people to talk to, so I didn't continue talking to him, as my purpose for signing up on that site was to find someone I could actually date who lived close enough to me for a relationship to actually work. I did tell him about WP before I stopped IMing him, but I don't know if he ever joined.
However, I'm still dating the first person I actually initiated contact with, so I didn't stay on the site long enough to notice any AS/NT ratio.
