The description of the app in the Apple Store is priceless:
Wanna say “good morning?” Just yo.
Wanna say “Baby I’m thinking about you?” – Yo.
“I’ve finished my meeting, come by my office” – Yo.
“Are you up?” – Yo.
According to the Urban Dictionary, yo is, among other things, “A contraction of the possessive prenominal adjective ‘your'”. But it’s much more, of course, and the astonishing popularity of this simplest of apps is being interpreted as a sign not only of our times but of an emerging digital dualism.Tweet
