How 'bout for the last week you intro a discussion about how electronic communication trends like e-mail and texting have diminished the "face time" and social interaction/integration of individuals? Does it help or hurt human interaction, the exchange of concepts and ideas... p'raps ask who's more likely to embellish or be more bold in the 'ether' than in RealLife situations, who would be less likely. There will be those who cite video conferencing, "Gotomeeting" etc. fer sure... BUT!
They're gonna be lookin' toward summer release anyway, make it a "free-for-all". Open discussion, debate. When the place gets really animated bring up the idea that THAT kind of interaction can't be duplicated ~electronically~ with any dynamic approaching RL exchange. :smirk
