> This tool demonstrates that Google is already accessing and indexing the data it says it needs to improve its search results. This isn't rhetoric; it's code.
It doesn't really demonstrate that. It demonstrates that Google can show G+ pages related to a topic, and that it can show high-ranked social pages linked to the owners of those G+ pages. But it doesn't show that on a broad, scalable basis Google can dependably link from a topic to a highly relevant 3rd-party social page. Demonstrating it on a couple of easy, celebrity-focused queries isn't proof of anything.
