In order to promote its Yahoo Personals online dating service, Yahoo arranged a special Valentine's Day promotion in Herald Square yesterday:

"Yahoo set up an eight-foot tall model of a haystack stuck with giant needles. Finding the right mate can seem as hard as finding a needle in a haystack... but in Yahoo's haystack, the needles were in plain sight, and everyone who grabbed a needle won a prize. The gifts ranged from one-pound bags of ground coffee from Dunkin' Donuts and heart-shaped boxes of Godiva chocolates to the top prize: diamond-encrusted hoop earrings - the real thing."

Not to be outdone, online dating rival Match.com displayed classic Magnum photos of couples on a digital billboard at the Port Authority Bus Terminal. The company also hired a photographer to take pictures of real-life New York couples as well in order to display them on the billboard.
