Yes. True and fair. But how can we test the page rank algorithm “ourselves"? Who is "we" in the "we do test them"? Is the public even asking for 3rd party examinations by transparent/public organizations (or at least, publicly funded)? Seems like we only get to "test" against the live system, and third party examination seems relatively impossible. It seems like something with such far reaching and invasive results should be more accessible, at the very least.
