Yo App Goes From Seriously Dumb to Surprisingly Useful

Yo’s all grown up, yo. The absurd smash-hit app that once only allowed users to send friends the word “yo” just went from useless to useful, and it’s not a joke.

Now the free social-networking app -- originally launched by San Francisco engineer Or Arbel as a joke last April Fool’s Day -- finally does a lot more than send monosyllabic salutations. It’s been redesigned to be a content notification clearinghouse, tipping users off to new videos, images and articles from an impressive mix of 150 partner websites.

To hook up to Yo’s steady fresh content drip, users log into the app as they normally would, then subscribe to notifications or “Yos” from the content channels they like from the app’s new Yo Store lineup.

Yo content channels are lumped into 10 basic categories including “productivity,” “business,” “news” and the all-important “fun.” Yo-ers can plug into LOL-worthy bits from the lighter side of the Internet -- Lil Bub, the web’s most famous feline, Funny Or Die and Cheezburger -- to news bursts from mainstream media outlets like BuzzFeed, USA Today and Daily Mail.
