I have recently been "coming out" to people about having Asperger's, and it has been very freeing. I have told a few people, and, to my surprised, they weren't surprised!
Two of them told me that they had even suspected that I have it! I had been so worried about people not believing me, but apparently that hasn't happened even once (actually, my little sister didn't think I had AS when I told her, but I don't think she has a great conceptualization of what it is). Coming out to people has been a really positive experience for me so far. My therapist had encouraged me, because she thought it would help people understand me better, and I think she was right. (As a note, the people I have told are mostly people in a clinical psychology grad school program with me, so they know more abour Asperger's than the general population.)
I guess this post doesn't have a specific point; I just wanted to share my surprise and happiness with my coming out experience.
