I wasn't searching for information on autism or AS. I believe the first time I ever heard of AS was from this site. I've always had the stereotypical AS problems interacting socially, but I didn't understand that being social was considered important, and didn't think about searching for other people with such problems because I rarely think about connecting with other people.
I was using Google search to see if anyone else had the same sensory issues I do, because any time I had expressed such an issue other people had been dismissive. I wanted to know if anyone else anywhere had any of the same sensory issues. One of the top results for a search was this site, and in the summary there was the phrase "our obsessions". I've had very persistent, very strong obsessions(especially one), so I clicked on the result, and this forum had so many pages of people telling stories that were similar to stories I could tell, or explaining things in the way I might explain things.
