I've been off the Twitter-Facebook grid for about two weeks. Just been buried at work and home; lots going on, in a good way.
But living without key social networks when I'm in the business of creating social networks has been an interesting experiment. That "digital silence" has crystalized some things for me in terms of how and when social media can be effective.
But tomorrow, plan is to dive back into Twitter, catch up on Facebook and immerse myself into finishing a PRD (product requirement document) for a cool new site we're building that'll stretch our social commenting efforts in new ways.
