All that reading.. I don't claim it has only downsides to the dynamic of the game. As others have stated, it probably exercises some cognitive brain function and trains you to be more attentive and capture essential stuff more easily, but this entry is not meant to debate that.
How would you like to speak and listen, instead of read and write?
Presumably every player has a microphone, doesn't need to be this one. And of course a sound playing device. A dedicated site or flash interface with visually appealing design facilitating the sharing of content optional.
So yeah .. that's about it, how do you like the idea?
You basically download the other guys` statements in the form of a mp3 file and listen carefully to the argumentations and even voice tone and style of speech, which is a whole additional dimension to what we have going on now. Likewise you add your vocal contribution when you get home or somewhere private like a university bathroom (taking a dump would be a whole new experience).
I wouldn't go so far as to include video feed, this would kind of be too problematic (privacy, people trolling you, the file would be too big etc) and I can't be bothered. But voice is definitely ok.
As for the people don't have time issue, which often times gets discussion and thus gameplay to stagnate, this could be slightly beneficial in that regard also. I mean you wouldn't go walking down the street from home to work with your iphone reading mafia posts, but you would be inclined to listen to them wouldn't you.
Imagine a brave new world where everybody finally has something cool to do while jogging, dying of boredom during some useless class, making the bed and brushing teeth, faking an orgasm etc.
IMO it's a good way to balance out that sleep, work, play ratio.
In closing here's a model so you buy in to the idea more easily, it's a proven marketing strategy.
