Newly diagnosed (last November) here. From what I've seen so far (and is confirmed in their own words), Autism Speaks has nothing to offer that is of any use or interest to me.

Conversely, I suspect that newly diagnosed adults such as myself have nothing to offer that is of any use or interest to them, since most of us already have a fairly good handle on who we are and what our life goals are, and aren't looking for some kind of treatment because we know perfectly well that there is nothing wrong with us: I predict that their marketing will continue to target the parents of newly diagnosed children.

I conjecture that Autism Speaks is not run for the benefit of autistics at all. Judging by their six areas of research emphasis, the company's intended customers are the biomedical industry, and autistic people are (or will be) its product.
