The fact, that there is no audio emoticons just shows. When i post sthg nice for you, I'd prefer a decent applause over your tiny icons - or let's say the sound of a half silent fart if you don't like, what you read ;) That would make me use the internet less often :)
No, but seriously, why isn't there sounds to comment on stuff? What a non-innovative strange disconnected image-based culture we have atm . . . !
