An excerpt from Facebook and Email are NOT Distractions, but Necessities, by Peter Shankman
You want to make money? You need to be where they [your customers] are. You need to get the competitive intelligence they’re offering. You need to listen to them. How do you do that? By making sure you know where they are, and being where they are.
Chances are, they’re on Facebook and email. Not using it because you’re too busy “running your business?” Good luck with that. You won’t be running your business for long.
