I said "Yo" the other day, shortly after signing up for the service. I was walking along the street (on the sidewalk) and a guy was backing out of his driveway in his car, and he wasn't paying attention to me, such that he might have backed into me. I said loudly "Yo" and the situation was resolved. Nothing else needed to be said.

That has nothing to do with this app, except the superficial name.

It does actually. the app influenced my offline behavior and it helped me realize that in many situations a "yo" will suffice

Isn't it pretty normal to say "yo!" in those situations anyway? I've never even heard about this app but I've done this for years.
