Oxford University Press Word of the Year

I got an e-mail this morning informing me that the Oxford University Press has compiled it's list of new and popular words from 2009, culminating in their selection of the 2009 word of the year:

unfriend

I understand the timeliness and social relevance of "unfriend," but it's kind of a downer of the word. Lexically, isn't the selection of "unfriend" as word of the year basically summing up 2009 as a year of variable friendships? Not so positive an idea.

Let's hope 2010 brings us words with more positive connotations.
