Pretty much every time you log on to Facebook or use Google, you’re participating, as a subject, in an A/B test. Unknowingly. Without informed consent. This is how privacy and human rights are eroded, one click at a time. Worse yet, the folks who do this brag about it! Don’t believe me? Type “A/B testing internet” into your favorite search engine (I avoid Google) and see what you get.
There’s a friggin’ geek army of snoops out there.
