Souzi - you're right that social media presents us with new communication opportunities like sharing that you've had a chicken salad sandwich for lunch or just completed a workout at the gym.

A 2009 study by Career Builder reported that 45% of employers did check social networks as part of their employment process, so the counsel you're providing is spot-on.  Good stuff -- thanks for sharing!
