Generational warfare in the 2010s: :) vs :-) Sep 20 2012
According to research done by Stanford University's Tyler Schnoebelen, the type of smiley you use is determined in part by your age.
Emoticons with noses are historically older. Since it is words that unite and distinguish clusters, this means that people who use old-fashion noses also use a different vocabulary -- nose users don't mention Bieber or omg.
I am obviously a non-noser because I am down, as we kids say, with Beibler and Carly Mae and Gandgum Style and Skillet. :) (via the atlantic)
