Thank you. With the person search, I can see where the data comes from 
that google is returning in search results. The site searches are 
accompanied by a google ad for the webmaster structured data tool, hehe.

It is disconcerting that if I try to show someone the value of adding 
metadata to html, I can't simply do a search and show them how the 
details are coming from metadata. In nearly all searches that I have 
done to test this, I can find no corresponding metadata on the page.
