I didn't see it like that. It makes perfect sense in the context it's being shown in: a personal wiki system. Even if such a system would be extended to the browser, I imagine the principle of auto-linking based on the user's already-accumulated knowledge would stay. And would be nothing like SEO spam, since it would link back to the user, not to some third party. I would still want to be able to distinguish regular links from generated ones (and the heatmap UI would allow that), and it would make it easy to spot and connect to my topics of interest in a larger body of text.
