By the time the US bowed out in an agonizing loss to Belgium in the Round of 16, I took it as hard as any Mets or Jets playoff defeat, as if I'd been following them for years rather than weeks. I had truly come to believe that we could win! By the time Argentina lost its nail-biter to Germany, I was questioning what I ever saw in American football's three-and-outs and relentless commercial breaks. Some of this feeling was definitely thanks to ESPN's slick marketing and broadcasting packages, and some of it was thanks to sharing the experience via social media, with friends and strangers alike.
