Cell-phone texting has become the preferred form of basic communication between teens and their friends, according to a new report from the Pew Internet & American Life Project. Daily text messaging among teens has increased in the past 18 months from 38 percent of teens texting friends daily in 2008, to 54 percent of teens texting daily in 2009. The average teen sends and receives 50 or more messages per day, or 1,500 per month.
