There is no e-mail being sent, but I think many people actually believe that the person they search is notified - would explain why so few people have used it in recent years.
Everyone who has searched for your name is listed in a sub-section / "tab", listed as a link on the same page where you can search for the information of others. I imagine that very few people are looking at that, especially not a few days after the initial "OMG now you can look up what everybody makes" articles in the newspapers.
