WTF, IT´S THAT SIMPLE!

So mindless. It’s only slightly less boring than “Holá” or “Hi,” if only because of some perceived aggression or excitement attached to it. But Yo is anything but simple. If you haven’t been following along on Twitter, Yo is the hottest new app that will leave you scratching your head. The entire premise of the app is to send other users a single word: Yo.

Yo currently has over 50,000 active users, after launching as a joke on April Fools’ Day. Users have sent over 4 million Yo’s to each other.

It might have started out as a joke, but the app has turned into something more universally enjoyable, and its brief popularity tells us something bigger about where the mobile social landscape is headed. We’re seeing the death of digital dualism play out before us, with apps focused on merging the physical and digital worlds. Snapchat has ephemerality. Whisper and Secret have anonymity.
