Pardon my SEO: Google uses both heuristics and partial execution of Javascript these days. Linking to things only through JS is not a good method to prevent Googlebot from stumbling upon them. I only mention this because a lot of people I know think that apparently Google's colony of well-paid supergeniuses has not written anything since like 2004.
No, this is a brand new site, on it's first index through Google. I'm very confident that they went through the JS. Nobody else had any link to the site at all yet. Not really on topic, here, but the parents comment inspired me to share.
