Excellent article. It applies to young adult kids too. My daughter, who didn't do Twitter, was hanging with a bunch of friends freshman year of college. They were berating her for not being on Twitter. She replied that her mom was on Twitter and her friends looked me up. "Wow, your mom's Twitter feed looks exactly like yours would if you were a little older and could be bothered. Your mom is totally rad." It was a proud parenting moment for me when she shared this story with me.
