While I agree that some better hinting is necessary, there is an About link at the top and it's not that hard to get some details about this project through it.

It's pretty intuitive except when you type a name that is very unpopular as a registered first name with social security (which is where the data comes from according to the blog posts behind the About link)

I thought the same thing about "rich people" - I guess he meant rich as in "rich dataset"

Turns out, if your browser isn't wide enough, the About link inexplicably disappears. (1152px is not wide enough, so I never saw it)

But even the About link, once visible, just links to they guy's blog of most recent posts. There is no direct "about" on that page.
