Facebook is perhaps the most prominent example, but the internet, whether we want to accept it or not, is a gigantic data-mining operation where every thing about us is monitored, measured and experimented with -- even our love life, should we choose. The folks over at online-dating service OKCupid (OKC) have recently detailed, among other things, how they futzed with the site's match-percentage system to see if it'd affect users' messaging habits. To start, OKC wanted to see just how much bearing system had on the likelihood of sending one message. When the service took two people who were actually 30 percent compatible and fudged the numbers by, say, 60 points, the amount of first messages sent naturally increased. As the OKTrends blog notes, that's exactly what was expected because that's how the site's users have more or less been trained; a higher number means a potentially better match. But, as anyone who's used the site can probably attest, one message doesn't mean a whole lot.
