Happy birthday, Greg!
Regarding the ranking, I'm not certain what you're asking. We have written to other Asperger's sites and requested links, and a handful are enthusiastically adding links. More links should increase the pagerank.
As for Google, I also have started a shoestring-budget AdWords campaign to get people to the site, which has gotten some clicks. I'm only spending up to 75¢ a day on it now, and I hardly ever see it when I do searches on asperger's anymore.
We also have decent meta tags on the site, I think, but I don't know how much search engines rely on meta tags anymore.
