OKCupid Publishes Findings of User Experiments - NYTimes.com

A stark reality check on "how websites work"

"“If you use the Internet, you’re the subject of hundreds of experiments at any given time, on every site,” Christian Rudder, president of OKCupid, wrote on the company’s blog. “That’s how websites work.” [...]  The test also illustrates how easy it is for a website to manipulate users without their knowing. The small number of users who received changed compatibility scores, some to 90 percent from 30 percent, were not told about the change before the experiment began. After the test ended, OKCupid sent emails revealing the true compatibility scores."
