Recent scores are not on the result page, but you can see them at the bottom of the play page.

Somewhat related, I'm amazed at how many Guest scores there are on quizzes. Are there more people that randomly come across and play a quiz from Google searches and whatnot than registered members?

"Are there more people that randomly come across and play a quiz from Google searches and whatnot than registered members?"

Yep. About 3 times as many guests as regular players on average. It's been this way since the site was created.

I try to invite friends and acquaintances to play quizzes, and they usually do, but I have a devil of a time convincing them to create profiles so that they can rate quizzes and also have a record of play and the other benefits of membership, even just regular membership (no fee). Some seem afraid that their information will be abused/sold or that they will get spam; others won't really tell me what the issue is, beyond "I'm on enough social media". But this isn't social media and predates social media, I tell them; it's a website and a community. And that, I suppose, is a fading feature of the Web that some folks just don't understand because of the dominance of social media.
