Looking for Someone

Inside the world of online dating:

If the dating sites had a mixer, you might find OK Cupid by the bar, muttering factoids and jokes, and Match.com in the middle of the room, conspicuously dropping everyone’s first names into his sentences. The clean-shaven gentleman on the couch, with the excellent posture, the pastel golf shirt, and that strangely chaste yet fiery look in his eye? That would be eHarmony.
