In-game, we do not have five-hour meetings. When we get a large group of people together for five hours, we are going to slaughter things by the thousand.
In-game, we do not spend the first half hour of our gathering engaging in a clever ice-breaker, to help get those creative juices flowing and put everyone in the right mental place for a free-wheeling discussion. We spend the first half-hour alt-tabbed, reading web pages while waiting for everyone to get to the right zone. We may also be discussing character builds or the latest test server notes on Teamspeak. (If anyone has a way for me to alt-tab from life during clever ice-breakers, please post it in the comments. No PDAs.)
