Hello Ashish the reason we set out to make an audio network is two fold.
1) when people post in their voice the message dos not loose the emotion and essence and hence what we see happening on the system is emotional connections between thought posters and listeners and commentators.
2) Audio enables people to speak in english, hindi, malayalm, bengali, gujrati and mix dialects, though we are yet to optimize the UI for other languages or a language agnostic UI but people have started posting in languages in which they think and are comfortable with. we believe that internet should be for everyone and we all usually understand more then one language when we hear it vs reading it. .
also we are seeing that people when hear other people , the conversation becomes more real and hence we have yet to see trolling
