Grammy socials

SOCIAL STUDIES: "By the way @Twitter," tweeted Paste magazine during the telecast, "pretty amazed the #Grammys are wiping #DowntonAbbey right off the socials tonight. Also, GO LUMINEERS!" It was a tribute to the infusion of young acts with genuine mass appeal, a raft of energetic performances and the show's canny production and direction that the Grammys dominated the trending topics on Twitter and generally stormed the social networks. There was considerable chatter about Fun., Mumford & Sons, Kelly Clarkson, Carrie Underwood, Justin Timberlake, The Lumineers and Miguel--not to mention that Sting guy and host LL Cool J. Who knew the dude from NCIS Los Angeles could rap? (2/10p)
