It really is strange, I can only credit its success so far to the fact that it's tapping into people's primal urge to be able to literally shout down the opposition instead of just metaphorically shout them down. I don't know why anyone would find the format of being forced to debate on the spot better than having the time to construct posts at your leisure. Every clip or story I've heard/seen come out of the app has been a completely mess.
