The difference between offline and online communication

One of the things I’ve been considering is the difference between offline and online communications. To me the people’s mic (or even one person speaks at a time) is al limitation of offline environments that we shouldn’t be emulating to replicate. Instead I would suggest a philosophy of harvesting lots of content simultaneously and providing mechanisms to filter the noise and promote the group sentiment – similar to the reddit approach.
