Yes, that's black hat SEO. It's very different from the Search Engine Land world. The idea is burn/rinse/repeat of sketchy affiliate sites, people make a very good living off it. Even still. Matt Cutts can surely find all he needs to know about that world on Black Hat World, I don't think that these guys are keeping much from them. But I also don't think it's easy for them to fix without potentially having negative consequences for the rest of the world.
The flip-side of this is the "white hat SEO" world. I don't know about Jill's own practices, but the conference/publication world with which she's a part of is frequented by people like Matt Cutts. And I think she hits the nail on the head for that: it's driven by content/PR now. There is still a place for on-page SEO for a corporate site if you're strong with the technical stuff (for example, schema.org type stuff is just getting off the ground with the Google Knowledge Graph). But it's not the sexy / easy to sell fast salvation that it once was.
