I joined Okcupid last year out of curiosity. (I wanted to observe people interacting through online dating sites but did not want to pay a monthly fee on one of the bigger sites)
After getting bored and several months of staying off the site, I decided to actually try it for dating and friend making. I added that I have asperger's syndrome, and I have gotten a lot of stupid messages since then. Some people seem to find it vaguely interesting, but have very little understanding of asperger's and have even less interest in learning more about it. Others just use it as an icebreaker - "so you have aspergers? thats cool. what food do you like?".
In the way of messages, I have gotten things like "it's ok [that you have asperger's] 'cause you're really pretty", "you're hot so you should be able to get a date anyway", "I used to be shy too but like meeting people and better selfesteem helps", and my favourite, in answer to me explaining that I want to date someone with similar interests to mine and don't think I could date someone with whom I share no interests, someone said "Yeah, but are you sure that's you or just the asperger's talking?"
I do think it is a good idea to let people know about the asperger's early when one is looking for a date; however, at least in my case, putting asperger's in one's profile can lead to a lot of asinine comments.
...maybe I have incorporated it into my profile poorly.
