When I first read about Blippy, a Twitter-like service that would allow my "followers" to get real-time updates about my credit or debit card purchases, and "like" or comment on them, a la Facebook, I rolled my eyes. Who cares what I just bought at Starbucks, and, more importantly, why would I ever want anyone to know? Who in their right mind would use this?

I had a similar reaction when I saw recent research from the Kaiser Family Foundation that found that today's eight-to-18 year olds spend an average of seven hours and 38 minutes every day using entertainment media-including cell phones, iPods, computers, video games and TV. When you account for the fact that they're often using more than one device at a time, they actually cram more than 10 hours and 45 minutes of media content into that 7.5 hours. The research also found heavy media users get lower grades and are less happy. The research left me wondering, "Who are these kids and what are their parents are thinking?"
