I don’t honestly know anything about the New Oxford American Dictionary or why I should care what they think – they’re not one of *my* 31 dictionaries – but I do like their word of the year, “unfriend.” As in, “Once a former colleague unfriended me because of  a comment I wrote on her Facebook status.” (She sheepishly refriended me a few weeks later – I’d never even noticed.)
