Would you use an audio social network? Looking for early feedback

I built a simple prototype of an audio social network voice vlogs, voice comments, no text feeds.

You simply need to hit the "Record" button and share absolutely any thought that comes to mind. For instance, you could mention the last movie you enjoyed and recommend it to others. You could ask a question like whether you believe in aliens or simply vent about some jerk who took your parking spot. Feel free! My prototype

Would love honest feedback: what works, what's confusing, would you actually use something like this?
