Apple took a step in the right direction with the do not disturb feature in the Notifications bar. When I don't want to be bothered, I turn it on, when I want to be chatty I turn it off. The next step should be apps that are aware of your do not disturb state and update your presence (as an option) when it's set. Then, I want a timer so I can get blasted with updates every 25 minutes like Pomodoro timer.
