Jim at the FBI Memos talks twitter.

Now, email is old school. Adults send three emails for every text. With teens, it is the other way around. Young consumers play by their own set of multi-tasking, micro-messaging rules. And most marketers are failing at getting any message through to them. In a world they completely don’t understand, marketers just assume more is better, and they increase the frequency of their old school messages. This is a generation that can do homework, chat on Facebook, keep up with Twitter and text messaging, all at the same time. According to a 2007 study by MTV and Microsoft, 14-24 year olds have an average of 53 people they consider friends. Multi-tasking is all they’ve ever known. They can filter the noise out.
