I could see the Tinder-style pivot actually making this an interesting app.
As it stands, what this app fails to do is establish a channel of communication. If I message a friend on Skype, I know that we're most likely going to converse over Skype. Same with email, SMS, phone call, etc. With Yo, however, they have to choose some method of communication which may not be ideal for me. Furthermore, given that there is zero metadata regarding the "Yo", they have no clue how urgent it is that they get in touch over some real communication channel. The only context that one can have around a Yo would have to be established before-hand (over a medium for real communication).
In fact, since there's no metadata (besides the identity of the sender), Yo is actually less useful than a beeper.

This might be the allure. Its a message without baggage. There's no guilt for failing to say "hey, how are you man?" No shame in saying "yo" and getting on with your life. Because it lacks the ability to "establish a channel of communication," it inherently removes social pressures to extend the communication to a degree one or both parties may not want at the moment.
That's an interesting theory, and something like that could have a place somewhere. It's unfortunate that one has to establish the grounds for such a relationship beforehand, by convincing someone to download this app that allows pinging between them and exactly one other person (until this app gets more traction).
